-// dear imgui: Platform Backend for QNX Screen
-// This needs to be used along with a Renderer Backend (e.g. OpenGL3, Vulkan).
-
-// Implemented features:
-//  [X] Platform: Keyboard support. Uses io.AddKeyEvent() and native QNX key symbols.
-//  [X] Platform: Mouse support. Handles position, three buttons and horizontal/vertical wheels.
-//  [X] Platform: Touch support. Maps the first active touch contact to the primary mouse button.
-//  [X] Platform: Focus and window-size updates.
-// Missing features or Issues:
-//  [ ] Platform: Clipboard support.
-//  [ ] Platform: Gamepad support.
-//  [ ] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors).
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

 // (minor and older changes stripped away, please see git history for details)
-//  2026-08-06: Fixed querying framebuffer scale when using Metal. (#5592)
-//  2026-07-15: Inputs: restore SDL_StartTextInput()/SDL_StopTextInput() in IME handler for on-screen keyboard support on Android/mobile. (#7636, #9474)
-//  2026-04-16: Made ImGui_ImplSDL2_GetContentScaleForWindow(), ImGui_ImplSDL2_GetContentScaleForDisplay() helpers return a minimum of 1.0f, as some Linux setup seems to report <1.0f value and this breaks scaling border size. (#9369)
 //  2026-02-13: Inputs: systems other than X11 are back to starting mouse capture on mouse down (reverts 2025-02-26 change). Only X11 requires waiting for a drag by default (not ideal, but a better default for X11 users). Added ImGui_ImplSDL2_SetMouseCaptureMode() for X11 debugger users. (#3650, #6410, #9235)
 //  2026-01-15: Changed GetClipboardText() handler to return nullptr on error aka clipboard contents is not text. Consistent with other backends. (#9168)
 //  2025-09-24: Skip using the SDL_GetGlobalMouseState() state when one of our window is hovered, as the SDL_MOUSEMOTION data is reliable. Fix macOS notch mouse coordinates issue in fullscreen mode + better perf on X11. (#7919, #7786)

 // CHANGELOG
 // (minor and older changes stripped away, please see git history for details)
-//  2026-10-06: Added support for dynamic rendering with multiple color attachments (PipelineRenderingCreateInfo.colorAttachmentCount > 1): we render to the first one and leave the others untouched. (#9574)
-//  2026-09-07: Round framebuffer dimensions to the nearest integer instead of truncating them. (#9538, 9515, #8628)
-//  2026-09-03: Added for support for multiple Vulkan contexts with custom loaders. (#6616)
-//  2026-04-23: Added support for standard draw callbacks (in platform_io): DrawCallback_ResetRenderState, DrawCallback_SetSamplerLinear, DrawCallback_SetSamplerNearest. (#9378)
-//  2026-04-22: *BREAKING CHANGE* redesigned to use separate ImageView + Sampler instead of Combined Image Sampler. This change allows us to facilitate changing samplers, in line with other backends.
-//              - When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler.
-//                - Before: ImGui_ImplVulkan_AddTexture(VkSampler, VkImageView, VkImageLayout)
-//                - After:  ImGui_ImplVulkan_AddTexture(VkImageView, VkImageLayout)
-//                - Kept inline redirection function that ignores the sampler.
-//              - When creating your own descriptor pool (instead of letting backend creates its own):
-//                - Before: need at least IMGUI_IMPL_VULKAN_MINIMUM_IMAGE_SAMPLER_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER.
-//                - After:  need at least IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE.
-//                                      + IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE       descriptors of type VK_DESCRIPTOR_TYPE_SAMPLER.
 //  2026-03-11: Vulkan: Added ImGui_ImplVulkan_PipelineInfo::ExtraDynamicStates[] to allow specifying extra dynamic states to add when creating the VkPipeline. (#9211)
 //  2025-09-26: [Helpers] *BREAKING CHANGE*: Vulkan: Helper ImGui_ImplVulkanH_DestroyWindow() does not call vkDestroySurfaceKHR(): as surface is created by caller of ImGui_ImplVulkanH_CreateOrResizeWindow(), it is more consistent that we don't destroy it. (#9163)
 //  2026-01-05: [Helpers] *BREAKING CHANGE*: Vulkan: Helper for creating render pass uses ImGui_ImplVulkanH_Window::AttachmentDesc to create render pass. Removed ClearEnabled. (#9152)

-
-
-Other Changes:
-
-- Style:
-  - `StyleColorsDark()`: tweaked WindowBg to be darker than in 1.93.0.
-  - Added `style.SymbolArrowSizeFactor`, `style.SymbolArrowThicknessFactor` to tweak the
-    shape and look of arrows. Made default arrow stroked. (#5233, #2431, #2235, #6730, #8243)
-    Legacy arrow: size: (0.60f,0.70f), thickness: 0.0f
-       New arrow: size: (0.72f,0.40f), thickness: 0.30f
-- Windows:
-  - Using `SetNextWindowPos()` with a pivot while a window is hidden and measuring
-    size will still apply temporary position until size is figured out. (#9568)
-- TreeNode:
-  - TreeNodeGetOpen(): added flags parameter to allow passing `ImGuiTreeNodeFlags_DefaultOpen`
-    or `ImGuiTreeNodeFlags_Leaf`. (#9569, #9592, #3823, #9251) [@adalisk-emikhaylov, @Yaki-Blake]
-- Popups:
-  - Modals: fixed an assert displaying a modal in an environment where
-    `io.DisplayFramebufferScale` is not an integer (regression in 1.93.0). (#9598)
-- Tables:
-  - Fixed various border overshooting issues, some mostly visible with transparent
-    borders and under specific conditions: (#4678)
-    - On non-scrolling tables, inner horizontal borders slightly overlapped
-      outer vertical ones with certain settings.
-    - On non-scrolling tables, clamping lower border coordinates to stay within
-      visible range (no visible change, but it makes ImDrawCmd AABB more sensible).
-    - Fixed vertical inner borders slightly overlapping bottom outer border.
-  - Fixed various issues using `ImGuiTableFlags_NoHostExtendX`/`_NoHostExtendY`:
-    - Fixed selectable highlight straying off the X2/Y2 clipping limit.
-    - Fixed parent window work rectangle affecting the Y2 clipping limit.
-    - Fixed the Y2 clipping limit overlapping bottom outer border.
-- Multi-Select:
-  - Fixed `ImGuiSelectionBasicStorage::GetNextSelectedItem()` reading one past the
-    end of storage when trailing items are unselected (#9604) [@MilosLord]
-- Drags: fixed handling of `ImGuiSliderFlags_WrapAround`: value could temporarily
-  escape the range when dragging fast. (#9612, #9611, #7749) [@swayie, @ocornut]
-- ColorEdit:
-  - ColorButton, ColorEdit, ColorPicker: fixed an issue rendering colors when
-    inside a `BeginDisabled(false)` block, caused by the alpha cancelling-out
-    code in 1.93.0. (#9511, #9613, #9614) [@tksuoran]
-- ImVec2: added a check for cases where a custom `IM_VEC2_CLASS_EXTRA` macro
-  adds an extra `operator=` to ImVec2. This isn't supported but should not
-  be needed as you should have a constructor to convert from your type to ImVec2.
-- CI: added some ARM64 builds. (#9593) [@Harishmcw]
-- Examples: renamed various helper batch files from build_win32.bat to build_win.bat
-  to reflect that they can also build X64 or ARM64, given the right environment.
-  Made the script detect the environment when needed (e.g. to specify library path).
-- Examples: added support for ARM64 in selected build_win.bat helpers. (#9593) [@Harishmcw]

------------------------------------------------------------------------
- VERSION 1.93.0 (Released 2026-10-14)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.93.0
-
-In 1.93.0, the `ImDrawList` rendering API has been improved to be more robust and
-more consistent over the whole range of shapes. The rendering now matches much closer
-to common vector drawing APIs, like html canvas. Improvements, like anti-aliased line
-endings and stroke position were added. The coordinates passed to the API are now
-consistently describing shape outlines.
-
-For code using custom rendering: some details are now rendered slightly differently
-(even if generally more consistent). The difference in rendering is in the range of
-half a pixel, but that can lead to issues like some lines now look blurrier or more
-transparent. All Dear ImGui widgets should appear identical or better.
-
-The rendering of common shapes was optimized when the shapes fall on integer coordinates
-(which is most of the UI). This includes skipping anti-aliasing when not needed, or
-using textures instead of tessellated geometry to draw round corners.
-The varying code-paths are designed to look indistinguishable from each others.
-
-New rendering code fixes some inconsistencies between graphics APIs
-(e.g. DirectX vs OpenGL) which are using different diamond exits rules.
-New code should work precisely the same regardless of which graphics API is used
-(note that using _StrokeLegacy mode can lead to the same old inconsistencies).
-
-New rendering code also deals better with animating thickness and rounding
-(integer values are recommended).
-
-While the current version doesn't make lots of visible use of the new features and
-facilities, they are among the pillars that will make it easier to create prettier
-contents, both for custom rendering and future versions of the library.
-
-Use `ImDrawFlags_StrokeLegacy` mode to emulate old rendering:
-- Per-primitive:      draw_list->AddLine(..., ..., ImDrawFlags_StrokeLegacy);
-- For a given scope:  draw_list->PushDrawFlag(ImDrawFlags_StrokeLegacy, true); draw_list->AddLine(...); draw_list->PopDrawFlag();
-- Globally:           ImGui::Checkbox("DefaultsToStrokeLegacy", &io.ConfigDebugDrawListDefaultsToStrokeLegacy);  // Map to a checkbox
-- Globally:           io.ConfigDebugDrawListDefaultsToStrokeLegacy = io.KeyShift;                                // Map on Shift
-
-Don't panic!
-Many applications will not notice any difference! You will more likely see
-differences if you used lots of direct `ImDrawList` calls for custom rendering.

-
-Breaking Changes:
-
-- ImDrawList:
-  - AddLine(): removed the (+0.5f,+0.5f) offset that was sneakily added to input coordinates. (#9504)
-    - This fixes inconsistencies in the API and matches the PathXXX API.
-    - By default, stroke thickness extends on both side of the given segment.
-      e.g for a "pixel-perfect" looking line with thickness=1.0f, coords should be passed as center of each ends of the line.
-    - Use `ImDrawFlags_StrokeLegacy` to use old offset if required. Or you can apply the offset manually!
-    - Generally better, simple and faster to use `AddLineH()`, `AddLineV()` functions added in 1.92.8.
-    READ IF YOU ARE MINDFUL OF PIXEL-PERFECTNESS IN YOUR CUSTOM RENDERING/WIDGETS:
-    - TRANSITION GUIDE FOR AXIS-ALIGNED LINES:
-      - When switching from legacy `AddLine()` values to `AddLineV()`, `AddLineH()` you can keep same inputs coordinates as before:
-        - Old `AddLine({x, y1}, {x, y2}, col)` --> `AddLineV(x, y1, y2, col);` // Vertical line.
-        - Old `AddLine({x1, y}, {x2, y}, col)` --> `AddLineH(x1, x2, y, col);` // Horizontal line.
-        - This will be equivalent and faster for thickness=1.0f lines.
-      - Since `AddLine()` use default stroke pos Center and `AddLineV()`, `AddLineH()` use Inside, thickness>1.0f strokes will differ.
-        Using `ImDrawFlags_StrokeCenter` will match old result more closely (aka look centered),
-        but is more likely to look blurry as it already did before.
-      - Read table below about StrokePos and the "Pixel-Perfect Rendering" guide if you care about pixel-perfect lines.
-    - TRANSITION GUIDE FOR DIAGONAL LINES:
-      - Your lines will appear offset by -0.5f pixels on each axis.
-        Being anti-aliased diagonal lines, they won't look particularly better or worse, just slightly offset.
-        It'll likely only be noticeable if you carefully combined them with other primitives for a pixel-perfect result.
-      - Old `AddLine({x1, y1}, {x2, y2}, col)` --> `AddLine({x1 + 0.5f, y1 + 0.5f}, {x2+ 0.5f, y2 + 0.5f}, col);`           // Same
-        or use `ImDrawFlags_StrokeLegacy`      --> `AddLine({x1, y1}, {x2, y2}, col, thickness, ImDrawFlags_StrokeLegacy);` // Offset by +0.5f + disable AA ends.
-        This reapplies the old offset, and should get you exactly the same result you previously
-        got for thickness=1.0f lines. But said result were previously sometimes ambiguous and
-        renderer-dependent. (#3116, #3258, #2441)
-      - Old code did not support anti-aliased ends, which could create gaps when rendering shapes out
-        of multiple contiguous lines instead of using `AddPolyline()`. There is a possibility that you
-        legacy code added fudge offsets here and there; which may not be necessary anymore if you use
-        `_AALineEnds`, or if you combine rendering of contiguous lines using `AddPolyline()`.
-  - AddRect(), AddCircle(), AddNgon(), AddEllipse(), AddTriangle(), AddQuad(): defaulting to "inside" stroke.
-    - All closed shapes with thickness=1.0f will appear identical.
-    - The difference for thickness>1.0f shapes may be minimal since very large strokes
-      were not well supported for widgets, but stroke will default inside widgets.
-  - AddCircle(), AddNgon(): removed -0.5f offset added to radius.
-    - This fixes inconsistencies in the API.
-    - Use `ImDrawFlags_StrokeLegacy` to use old method if required. Or you can apply the offset manually!
-  - AddRectFilled(): non-integer coordinates will now display anti-aliased edges.
-    Previously, non-integer coordinates rendered with aliased edges snapped by the
-    rasterizer. (#6971)
-  - AddRect(), AddRectFilled(): rectangles with inverted coordinates won't be visible
-    unless using `ImDrawFlags_StrokeLegacy` mode. With inverted coordinates (min > max):
-      - Legacy `AddRect()` rounding off       -> visible but incorrect outer size.
-      - Legacy `AddRect()` rounding on        -> visible but very glitchy.
-      - Legacy `AddRectFilled()` rounding off -> visible and correct.
-      - Legacy `AddRectFilled()` rounding on  -> visible but very glitchy.
-      - Use `ImDrawFlags_StrokeLegacy` to use old rendering for cases without rounding, or fix coordinates.
-  - Merged `ImDrawListFlags` into `ImDrawFlags`. `ImDrawListFlags` was rarely used directly
-    and generally setup by the ImGui context. 
-      - `ImDrawListFlags_AntiAliasedLines`    -> `ImDrawFlags_AALines`
-      - `ImDrawListFlags_AntiAliasedFill`     -> `ImDrawFlags_AAFill`
-      - `ImDrawListFlags_AllowVtxOffset`      -> `ImDrawFlags_UseVtxOffset`
-      - `ImDrawListFlags_TextNoPixelSnap`     -> `ImDrawFlags_TextNoPixelSnap`
-    Unifying them allows easily using them for both per-primitives and scope alterations.
-    Kept redirection enums (will obsolete).
-  - Renamed all `ImDrawFlags_RoundCornersXXX` flags to `ImDrawFlags_RoundXXX`.
-      - `ImDrawFlags_RoundCornersAll`         -> `ImDrawFlags_RoundAll`
-      - `ImDrawFlags_RoundCornersNone`        -> `ImDrawFlags_RoundNone`
-      - `ImDrawFlags_RoundCornersTopLeft`     -> `ImDrawFlags_RoundTopLeft`
-      - `ImDrawFlags_RoundCornersTopRight`    -> `ImDrawFlags_RoundTopRight`
-      - `ImDrawFlags_RoundCornersBottomLeft`  -> `ImDrawFlags_RoundBottomLeft`
-      - `ImDrawFlags_RoundCornersBottomRight` -> `ImDrawFlags_RoundBottomRight`
-      - `ImDrawFlags_RoundCornersTop`         -> `ImDrawFlags_RoundTop`
-      - `ImDrawFlags_RoundCornersBottom`      -> `ImDrawFlags_RoundBottom`
-      - `ImDrawFlags_RoundCornersLeft`        -> `ImDrawFlags_RoundLeft`
-      - `ImDrawFlags_RoundCornersRight`       -> `ImDrawFlags_RoundRight`
-      - `ImDrawFlags_RoundCornersMask_`       -> `ImDrawFlags_RoundMask_`
-    Kept redirection enums (will obsolete).
-  - Marked `ImDrawListFlags_AntiAliasedLinesUseTex` and `style.AntiAliasedLinesUseTex` as
-    obsolete, as the new line rendering code always uses textures.
-  - Enabling `ImFontAtlasFlags_NoBakedLines` in the font atlas will now disable support for
-    anti-aliased lines by clearing `style.AntiAliasedLines`/`style.AntiAliasedLineEnds`.
-- Style: obsoleted `style.CurveTessellationTol` (default 1.25) which was in Pixels² unit in
-  favor of `style.CurveTessellationMaxError` (default 1.12) which is in Pixels unit. It is
-  easier to tweak + this allows us to easily scale error threshold on high density screens.
-  - style.CurveTessellationMaxError == sqrtf(style.CurveTessellationTol).
-- ImGuiTextFilter: removed `float width` parameter of `Draw(const char* filter, float width)`:
-  prefer using `SetNextItemWidth(float)` which is standard. Kept inline redirection function.
-- Fonts: renamed `AddRemapChar()` to `AddRemapCodepoint()` (rarely used, marked internal).
-  (#609, #5748, #9559)
-- Backends:
-  - DirectX12: Removed support for legacy `ImGui_ImplDX12_Init()` signature, which was
-    obsoleted in 1.91.6 (December 2014), because it needed to forcefully disable support
-    for `ImGuiBackendFlags_RendererHasTextures`. Use the new signature! (#9487)
-  - OpenGL3: Does not attempt to read `GL_CLIP_ORIGIN` by default as the detection is
-    sub-optimal and not reliable on some setup. Use `ImGui_ImplOpenGL3_SetClipOrigin(0)`
-    to enable auto-detection, or e.g. `ImGui_ImplOpenGL3_SetClipOrigin(GL_UPPER_LEFT)`.
-
-Other Changes:
-
-- Style:
-  - StyleColorsDark(): minor refresh of the default style to look more modern:
-    - Changed WindowBg to use a slightly greyer value and removed opacity.
-    - Changed FrameBg values to use a dark black to make frames stand out better.
-    - Tweak TextDisabled, TableHeaderBg, TableBorders to match altered WindowBg.
-  - StyleColorsLight(): inverted `ImGuiCol_TitleBgXXX` colors so that the selected
-    window title bar appears brighter.
-- ImDrawList:
-  - Added flags to specify stroke position in all `ImDrawList` stroking functions: (#9504) [@memononen]
-    - `ImDrawFlags_StrokeInside` (default for Rect, Circle/Ellipse, Triangle, Quad, Ngon + AddLineH, AddLineV)
-    - `ImDrawFlags_StrokeCenter` (default for Line, Polyline, Beziers, Paths function)
-    - `ImDrawFlags_StrokeCenterBiased` (center w/ bias for pixel perfect alignment)
-    - `ImDrawFlags_StrokeOutside`
-    - `ImDrawFlags_StrokeLegacy` (match old behavior)
-    - Legacy mode may be set as default for a given scope using `PushDrawFlag(ImDrawFlags_StrokeLegacy, true)`.
-    - Legacy code was generally applying +0.50f offsets which meant that,
-      - with thickness=1.0f: the stroke would appear inside.
-      - with thickness>1.0f: the stroke would start expanding on both sides but starting from that small initial offset.
-      - with thickness>1.0f for even integer values, the stroke would look blurry.
-      - TL;DR; the logic didn't make much sense for thickness>1.0f.
-    - Defaulting to Inside for closed shapes ensure that rectangles and lines are
-      never blurry, regardless of thickness, as long as input coordinates/sizes
-      are integers. (#9359) Recap:

-    - Read our Wiki guides for more details!
-        https://github.com/ocornut/imgui/wiki/Draw-List
-    - And interactive 1.92.9 vs 1.93.0 comparing testbed:
-        https://www.dearimgui.com/docs/drawlist_v193
-  - AddPolyline(), PathStroke(), AddTriangle(): the algorithm to render lines got overhauled.
-    (#9504, #2183, #2964, #7972 + #9360, #6331, #4250, #4091) [@memononen]
-    - Generally fixed rendering of thick strokes/paths.
-    - The new stroke expansion now uses corner miter calculation, which keeps thickness along
-      the line segments consistent. If the corner becomes too sharp, it will be beveled to
-      avoid long spikes at corners.
-    - There are also some robustness measures for the case where the line thickness is larger
-      than the features being drawn.
-    - Rendering artifacts are still possible when the path features are smaller than line thickness,
-      but the artifacts should be more localized. The new implementation attempted to favor simple
-      implementation and robustness over the corner case accuracy.
-  - All functions: new rendering code fixes some inconsistencies between graphics APIs
-    (e.g. DirectX vs OpenGL) which are using different diamond exits rules. New code should
-    work precisely the same regardless of graphics API. (#3116, #3258, #2441) [@memononen]
-  - Debug: added `io.ConfigDebugDrawListDefaultsToStrokeLegacy` to facilitate comparing old/new
-    behaviors. This is equivalent to calling `PushDrawFlag(ImDrawFlags_StrokeLegacy, true)`
-    on every drawlists.
-    Suggested uses, e.g.
-      - `io.ConfigDebugDrawListDefaultsToStrokeLegacy = io.KeyShift; // Map on holding Shift`
-      - `ImGui::Checkbox("DefaultsToStrokeLegacy", &io.ConfigDebugDrawListDefaultsToStrokeLegacy);`
-  - Added `ImDrawFlags_AALineEnds` flag to enable anti-aliased line ends.
-    - Most noticeable for thick lines.
-    - Also helps fill minor gaps if combining multiple individual lines. For best looking
-      continuous lines you should use AddPolyline(), it creates joins between line segments
-      to avoid any gaps.
-    - Added `style.AntiAliasedLineEnds` in ImGui to set default state.
-    - This is disabled by default! Enabling AA Ends by default would be more "correct",
-      but since it is very slightly slower and increases vertex/index data we decided
-      to not enable it by default.
-      This keeps situations such as "throw tens of thousands of lines at ImDrawList"
-      optimal. You can opt-in for a given shape or in a scope using `PushDrawFlag()`.
-  - Added `ImDrawFlags_JoinMiter` flag to disable using beveled corner.
-    - Closer to legacy rendering and slightly faster, but corners sharper than
-      90 degrees may expand far out.
-    - Automatically used by AddRect(), AddCircle(), AddNgon(), AddEllipse() functions
-      since we know that the input path does not contain sharper corners.
-  - Added `ImDrawFlags_CapSquare` flag to extend lines ends using square caps. (#9360)
-  - AddConvexPolyFilled()/PathFillConvex(): improved to handle input geometry more robustly.
-    The rendering of sharp corners was improved. Earlier there were issues with sharp corners
-    either creating long spikes, or messing up the adjacent edge's anti-aliasing. Now the
-    anti-aliasing fringe calculation is more consistent, and sharp corners get beveled to
-    avoid spikes. There might still be issues when the smallest extent of a long thin polygon
-    is less than a pixel. Also supports `ImDrawFlags_JoinMiter`, to facilitate matching
-    a stroke using the same flag.
-  - `AddRect()`, `AddRectFilled()`: various optimizations for rounded rectangles. (#1962, #9504)
-    - Integer-aligned coordinates and thicknesses will automatically use baked textures,
-      saving on both CPU and vertex/index data.
-    - Enabled by default. Use `ImFontAtlasFlags_NoBakedRoundCorners` to disable baking
-      round corners in font atlas.
-    - Added `ImDrawFlags_UseTexForRoundCorners` flag to enable in scope or per-shape.
-      Added for consistency and debugging, not really needed in practice.
-  - `AddCircle()`, `AddCircleFilled()`: fixed large circles being under-tessellated
-    (when above ~140 with default CircleTessellationMaxError).
-  - Improved debug-build performance in various locations.
-  - Improved minor mismatches when overlapping strokes and filled shapes.
-    For example, when using inside strokes,
-    - `AddRect()` and `AddRectFilled()` with rounding now overlap better. (#3656)
-    - `AddCircle()` and `AddCircleFilled()` now overlap better.
-  - Added `ImDrawList::PushDrawFlag()`/`PopDrawFlag()` to alter certain flags for a
-    scope and a given `ImDrawList`. (#9489)
-    - e.g. `PushDrawFlag(ImDrawFlags_StrokeLegacy, true);` enforce legacy tweaks.
-  - About `ImDrawFlags_StrokeLegacy`:
-    - This is designed to emulate old behavior:
-      - Most shapes use `ImDrawFlags_StrokeCenter`.
-      - AddLine() add +0.5f,+0.5f offset to position.
-      - AddRect() and AddRectFilled() allow inverted positions.
-      - AddRectFilled() has no AA when passed non-integer coordinates.
-      - AddCircle(), AddNgon() add a -0.5f offset to radius.
-      - Closed shapes use miter corners.
-      - Lines don't have anti-aliased ends.
-    - But there are known difference between legacy code and ImDrawFlags_StrokeLegacy:
-      - Thick shapes with acute angles will now preserve thickness better,
-        which may make them appear as protruding a little more.
-  - About disabling anti-aliasing:
-    - Disabling anti-aliasing is now emulated by applying different UV coordinates.
-      - It does not result in a performance increase or vertex/index data decrease any more
-        (however the tendency is that the new code behaves better than old code).
-      - But may be a useful stylistic choice in some circumstances.
-    - Many thick shapes had broken corners with old no-AA code, and the old no-AA code
-      was wildly different from the AA code. Not the case any more. (#288)
-  - Per-viewport FramebufferScale for Apple/Retina screen is applied to draw lists:
-    - AA Fringe is scaled accordingly. (#9577)
-    - Circle and Curves tessellation error are scaled accordingly.
-  - Reworked assert in `PushTexture()` to allow convenience grace period of using a
-    texture that was queue for destroy during the frame. Make it safe to stick to
-    an existing texture during the frame. (#9528, #8465)
-  - Added optional `platform_io.DrawCallback_SetSamplerFromTex` standard backend-agnostic
-    draw callback for requesting to use the sampler associated already associated to a texture.
-    Currently only supported by the OpenGL2/3 and SDLRenderer3 backend. (#9378)
-  - Fixed dangling `ImDrawList::_OwnerName` when using animated label. (#9552) [@ubi-dcastonguay]
-- Mixed Values:
-  - Added `ImGuiItemFlags_MixedValue` flag for representing mixed/indeterminate values.
-    Supported by: Checkbox(), RadioButton(), DragXXX(), SliderXXX(), InputXXX(), ColorXXX()
-    and Combo() functions.
-    The scoped flag is designed for usage by advanced property editors. (#5518, #5677, #6865)
-- Drags, Sliders:
-  - Ongoing drags may be cancelled using Right-Click, Escape or Gamepad Triangle.
-    Cancelling reverts to the initial value. (#8564, #9534)
-  - Fixed an overflow using `ImGuiSliderFlags_Logarithmic` with S32/S64 types which
-    leads to clamped interactions. (#9526, #3361, #1823, #1316, #642) [@lailoken]
-- TreeNode:
-  - Fixed issues/asserts with 32+ deep trees when using ImGuiTreeNodeFlags_DrawLinesXXX
-    features or other features requiring stack storage. (#9509) [@lasrod]
-- TabBar:
-  - Improved scroll target when clicking a Tab that is larger than the scrolling
-    section width.
-  - Using <> scrolling buttons while the selected Tab is at either end of the
-    section mid-section but not fully visible always makes it fully visible
-    (before eventually selecting a Tab in the leading/trailing section).
-- Tables:
-  - Fixed a bug restoring correct .ini columns order when table use is Sortable
-    but had no user changes. (regression from 1.92.9). (#9519, #9108)
-  - Fixed a bug tracking topology changes (insert new columns in the middle)
-    when the table is not _Reorderable: new columns would be ordered incorrectly.
-    (#9570, #9108, #9572) [@lailoken]
-- InputText:
-  - Fixed a crash in some cases when using Home key in a WordWrap+ReadOnly field. (#9561)
-- Selectable:
-  - Fixed `ImGuiSelectableFlags_SelectOnNav` triggering during NavInit.
-- Fonts:
-  - Reworked `AddFontDefault()` to use `io.DisplayFrameBufferScale` as part of the heuristic
-    to select `AddFontDefaultVector()` by default, effectively using ProggyForever instead of
-    ProggyClean on most Apple/Retina setups by default.
-  - Added `ImFont::AddRemapCodepointToGlyphIndex()` allowing to access glyphs that are not
-    mapped to codepoints. (#9559, #5647, #609, #5748, #8466)
-  - imgui_freetype: Fixed blurriness  rendering `AddFontDefaultVector()`. Caused by a
-    non-pixel aligned offset caused by `ExtraSizeScale`. (#9348, #9233) [@redpartizan, @RDMCz]
-  - (Internal) ImFontLoader: reworked `FontSrcContainsGlyph`, `FontBakedLoadGlyph` signatures
-    to take raw glyph index instead of codepoint. Added `FontSrcGetGlyphIndexFromCodepoint`.
-    (#9559, #5647, #9540, #8466, #8465)
-  - Added `IMGUI_DISABLE_STB_TRUETYPE` to completely omit the stb_truetype loader
-    code + stb_truetype.h code. (#9573)
-- ColorEdit:
-  - ColorButton, ColorEdit, ColorPicker: cancel-out alpha caused by `BeginDisabled()` so
-    disabled color buttons have the same color as non-disabled oness. (#9511)
-  - ColorButton: fixed issues/inconsistencies with checkerboard rendering when combining
-    color alpha and global style alpha. (#9511) [@enjmiah, @ocornut]
-- Popups:
-  - Amended context menu right-click opening code to check that the right-click
-    hasn't been owned by another items. This is more correct and also necessary
-    to avoid Drags/Sliders cancelling also triggering a cancel menu. (#8564, #9534)
-  - Reworked `GetMousePosOnOpeningCurrentPopup()` to be legal to call within the
-    BeginPopup/EndPopup scope of a popup which was just closed. (#9551) [@jkunstwald]
-- ImGuiTextFilter:
-  - Added support for space as an "and" filter, which is the standard. (#2435, #30)
-     e.g. w/ filter 'hello world' (without quotes) both words needs to be in input data.
-  - Added support for double-quoted "xxx" blocks to e.g. match words sequences. (#2435)
-     e.g. w/ filter "hello world" the exact sequence needs to be in input data.
-  - Fixed filtering when mixing "include" and "-exclude" keyword so that an "-exclude"
-    match always filters out. (#2435) [@kudaba, @ocornut]
-  - Added `DrawWithHint()` function. (#6206, #6395, #6447)
-  - Added a "incl -excl" hint by default when the search field is empty. (#6206, #6395, #6447)
-- Widgets:
-  - Checkbox, Menus: check marks use anti-aliased ends.
-  - Tweaked rendering in various locations to avoid blurriness:
-    - Windows: title-bar and menu-bar border (when thickness>1.0f).
-    - SeparatorText: border (when thickness>1.0f).
-    - Tree: hierarchy lines (when thickness>1.0f).
-    - InputText: input caret (when thickness>1.0f).
-    - TabBar: selected overline border (when thickness>1.0f).
-- Misc:
-  - Fixed `GetBackgroundDrawList()`/`GetForegroundDrawList()` not being properly reset
-    every frame when accumulated  session time is very large (e.g. a few days). [@lailoken]
-  - Added `IM_NODEBUGSTEP` helper to tag functions with `__declspec(non_user_code)` (MSVC)
-    or `[[gnu::artificial]]` (Clang/GCC) in order to provide a hint to debuggers to skip
-    trivial functions when stepping into.
-  - Tagged various trivial functions using `IM_NODEBUGSTEP`: `ImVec2()`, `ImVec4()` etc.
-    and various operators.
-  - Fixed strict aliasing violation in `ImHashData()` affecting Clang 23 + SSE 4.2 + -flto.
-    Could manifest as `ImFontAtlasBakedGetId()` computation omitting font size from
-    the hashed data. (#9557, #9560) [@sthalik]
-  - IO: restore default clipboard/ime/shell platform handlers on `ClearPlatformHandlers()`, fixing
-    issues switching backends mid-session to one relying on default. (#9537, #8945, #2769) [@lstalmir]
-- Demo:
-  - Added `Widgets->Mixed Values` section. (#5518, #5677, #6865)
-  - Custom Rendering section: exposed new flags; showcasing overlapping strokes
-    and filled shapes; added an option to animate thickness; added new shapes
-    to showcase new rendering features that previously hit limitations.
-  - Style Editor: fixed style/colors combo box applying style when opening Combo.
-- Backends:
-  - QNX: added QNX Screen backend. (#9492) [@mgorchak-blackberry]
-  - Metal, Metal4: added support for rendering inside a render pass with multiple color
-    attachments (e.g. when merged with other passes): we render to the first color attachment
-    and leave the other ones untouched. (#9574) [@tqjxlm]
-  - OpenGL2, OpenGL3: added support for `platform_io.DrawCallback_SetSamplerFromTex` draw
-    callback to request using the sampler associated already associated to a texture. (#9378)
-  - OpenGL2, OpenGL3: fixed `DrawCallback_ResetRenderState` handler not resetting all states
-    in the glTexParameter() path. (#9378)
-  - OpenGL3: added `ImGui_ImplOpenGL3_SetClipOrigin()` to specify origin between
-    `GL_LOWER_LEFT` (new default), `GL_UPPER_LEFT` and `0` (autodetect, old default).
-  - OpenGL3: avoid querying `glGetIntegerv(GL_CLIP_ORIGIN)` multiple times when using
-    when using default and using `DrawCallback_ResetRenderState`, at it appear to stall
-    some drivers. (#2186, #3998, #3146, #3143, #8640)
-  - SDL2: fixed querying framebuffer scale/density when using Metal without
-    going through a SDL_Renderer. (#5592) [@lailoken]
-  - SDLRenderer3: restore any temporarily modified texture scale modes at the of `RenderDrawData()`. (#9378)
-  - SDLRenderer3: expose CurrentScaleMode in ImGui_ImplSDLRenderer3_RenderState. (#9543, #9378) [@Clownacy]
-  - SDLRenderer3: added support for `platform_io.DrawCallback_SetSamplerFromTex` draw callback to request
-    using the sampler associated already associated to a texture via `SDL_SetTextureScaleMode()`. (#9378)
-    It is equivalent to setting `render_state->CurrentScaleMode = SDL_SCALEMODE_INVALID`.
-    Note: this  callback is only supported by selected rendering backends: most other graphics API
-    don't have the equivalent of `SDL_SetTextureScaleMode()` and the callback won't work with them.
-  - Vulkan: added for support for multiple Vulkan contexts with custom loaders. (#6616) [@lstalmir]
-  - Vulkan: added support for rendering inside a render pass with multiple color attachments
-    (e.g. when merged with other passes): we render to the first color attachment and leave the
-    other ones untouched. (#9574) [@tqjxlm]
-  - WebGPU: fixed passing non-integer sizes to `wgpuRenderPassEncoderSetViewport()`
-    when `FramebufferScale` is >1.0f. (#9515, #8628) [@WayU]
-  - WebGPU: update to build with wgpu-native 29.0+. (#9377, #9532, #9530) [@lucascompython, @ivan-enzhaev]
-- Examples:
-  - All: all examples now default to use a little bit of rounding (`FrameRounding` and `GrabRounding`).
-  - MSVC: disabled /JMC in Visual Studio projects (unnecessary overhead).
-  - GLFW/SDL2/SDL3+WebGPU: fixed running with wgpu-native missing `wgpuInstanceWaitAny()`. (#9377)
-  - GLFW/SDL2/SDL3+WebGPU: better select surface format. (#9576) [@ypujante]
-  - GLFW+Metal: fixed mistakenly calling `ImGui_ImplGlfw_InitForOpenGL()`, which
-    broke multi-viewport support. (#9564) [@ypujante]
-  - SDL2+Metal: create Metal context without using a `SDL_Renderer`.
-  - QNX+OpenGL3, QNX+Vulkan: added QNX Screen examples. (#9492) [@mgorchak-blackberry]
-  - OSX+OpenGL3: added example_apple_opengl3/ (OSX/Cocoa + OpenGL 3.2 Core profile).

- VERSION 1.92.9b (Released 2026-07-31)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.92.9b
-
-Changes:
-
-- DragXXX, SliderXXX: fixed a regression in 1.92.9 where clicking a previously
-  Ctrl+Clicked field would flick it to text edit mode for a frame. (#9476, #701)
-- Tables:
-  - Fixed Y2 position of lower horizontal border (ImGuiTableFlags_BordersOuterH)
-    being off by one pixel when vertical ones are not also enabled. [@thedmd]
-  - Fixed X position of angled borders being off by half a pixel. [@thedmd]
-- ImDrawData: fixed a regression in 1.92.9 where legacy `ImDrawData::CmdListsCount` was always 0.
-  Prefer using `ImDrawData::CmdList.Size` anyway.
-
-
------------------------------------------------------------------------
- VERSION 1.92.9 (Released 2026-07-25)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.92.9
-
-Breaking Changes:
-
-- DragXXX, SliderXXX, InputScalar: with `ImGuiItemFlags_LiveEditOnInputScalar` now
-  defaulting to being disabled: inputting a value with the keyboard doesn't write
-  intermediate values to the backing variable. (#9476)
-    Before: DragFloat() with user typing "123" --> write back 1, then 12, then 123.
-    After:  DragFloat() with user typing "123" --> write back 123 when validated/unfocused.
-  You can enable the flag back for a given scope if needed by specific widget/behavior.
-  Read below for details.
-- TreeNode: commented out legacy name `ImGuiTreeNodeFlags_SpanTextWidth` which
-  was obsoleted in 1.90.7 (May 2024). Use `ImGuiTreeNodeFlags_SpanLabelWidth`.
-- ColorEdit: obsoleted SetColorEditOptions() function added in 1.51 (June 2017) in favor
-  of directly poking to io.ConfigColorEditFlags. More consistent and easier to discover.
-- Drag and Drop: commented out legacy name `ImGuiDragDropFlags_SourceAutoExpirePayload`
-  which obsoleted in 1.90.9 (July 2024). Use `ImGuiDragDropFlags_PayloadAutoExpire`.
-- ImDrawData: marked `CmdListsCount` as obsolete (technically was obsoleted in 1.89.8).
-    Before: `draw_data->CmdListsCount`, After: `draw_data->CmdLists.Size`.
-
-Other Changes:
-
-- LiveEdit on/off: added `ImGuiItemFlags_LiveEditOnInputText` and `ImGuiItemFlags_LiveEditOnInputScalar`
-  flags to configure the timing of applying edits of backing variables when typing
-  values using a keyboard.
-  (#9476, #701, #3936, #3946, #5904, #6284, #8149, #8065, #8665, #9117, #9299, #700, #1351,
-   #1875, #2060, #2215, #2380, #2550, #3083, #3338, #3556, #4373, #4714, #4885, #5184,
-   #5777, #6707, #6766, #8004, #8303, #8915, #9308)
-  - ImGuiItemFlags_LiveEditOnInputText is enabled by default (same as before):
-    - The expectation is that for strings/text, enabling LiveEdit is a better default.
-  - ImGuiItemFlags_LiveEditOnInputScalar is disabled by default (new behavior):
-    - The expectation is that for numeric/scalars values, disabling LiveEdit is a better default.
-  - Until now:
-    - Edits where always applied immediately to backing variable, which is equivalent
-      to the `ImGuiItemFlags_LiveEditXXX` flags being enabled.
-    - Typing '123' in an integer field would output successively 1, 12 then 123.
-    - Most uses of `IsItemDeactivatedAfterEdit()` or `ImGuiInputTextFlags_EnterReturnsTrue`
-      were actually workarounds for this issue. Advanced applications would typically
-      use `IsItemDeactivatedAfterEdit()` to distinguish transactions.
-      Workarounds often required a backing store for scalar values, and there were
-      also a few niggles related to `IsItemDeactivatedAfterEdit()` when using +/-
-      buttons of an `InputInt()` widgets.
-    - Many of those situations can now be naturally simplified when disabling
-      `ImGuiItemFlags_LiveEditOnInputScalar` is disabled.
-  - The new flags allows disabling this behavior selectively for strings fields
-    such as `InputText()` vs scalar fields: `SliderInt()`, `InputFloat()`, etc.
-    - When LiveEdit is disabled, edits are applied when pressing enter, tabbing out,
-      clearing a field or deactivating due to a focus loss.
-    - The flag may be altered programmatically, e.g. for the entire frame scope:
-        NewFrame();
-        PushItemFlag(ImGuiItemFlags_LiveEditOnInputScalar, true); // Enable for scalars for the whole frame
-        ....
-        PopItemFlag();
-        EndFrame();
-      Or for a specific widget:
-        PushItemFlag(ImGuiItemFlags_LiveEditOnInput, true);       // Enable for one widget
-        SliderInt(...);
-        PopItemFlag();
-  - We intentionally are not adding `io.ConfigLiveEditXXX` fields to dictate the
-    default value of each `ImGuiItemFlags_LiveEditXXX`, because this is not expected
-    to be a user preference but a programmer/widget preferences.
-    And we strive to make the toolkit consistent.
-- Windows:
-  - Clicking on a window's empty-space to move/focus a window checks
-    for lack of mouse button ownership. This gives an additional opportunity
-    for user code to bypass it without using a clickable item. (#9382)
-  - Clicking on a window's empty-space to move/focus a window checks
-    for lack of queued focus request. (#9382)
-  - Fixed double-click collapse toggle not owning the mouse button. If a
-    `SetNextWindowPos()` with pivot was queued in the same frame, the second
-    click could trigger another item in the same window. (#9439) [@Cleroth]
-- Popups:
-  - Added bool return value to `OpenPopup()`, `OpenPopupOnItemClick()` functions
-    to notify when the popup was just opened. (#9429)
-- InputText:
-  - Added `style.InputTextCursorSize` to configure cursor/caret thickness. (#7031, #9409)
-    It is automatically scaled by `style.ScaleAllSizes()`.
-  - Reworked `io.ConfigInputTextEnterKeepActive` mode so that pressing
-    Ctrl+Enter or Shift+Enter still allows to deactivate. (#9239)
-- Tables:
-  - Redesigned/rewrote code to reconcile columns and settings on topology changes. (#9108)
-    - When a column label is passed to TableSetupColumn(), the underlying identifier
-      is used to match live columns data and .ini settings data when changing.
-      This makes it possible to add/remove columns from a table without losing
-      neither live data neither .ini settings data.
-    - PS: Note that this is distinct from toggling column visibility or reordering
-      columns, which was always possible. The new matching makes it easier to create
-      tables that are entirely customized by user or code, without losing state.
-    - Columns without identifiers or with duplicate identifiers are matched
-      sequentially, matching old behavior.
-    - Column ID are stored in .ini file.
-    - Code is being tested both for live topology changes and for loading .ini
-      data with mismatched topology.
-  - Context Menu: added a "Reset" sub-menu with a "Reset Visibility" option.
-    (which is greyed out when using default settings)
-  - Headers: fixed label being clipped early to reserve space for a sort marker
-    even when no sort marker is displayed. Auto-fitting a column still accounts
-    for the possible marker, so that sorting after an auto-fit doesn't clip the label.
-- Multi-Select:
-  - Reworked `ImGuiMultiSelectFlags_NoAutoSelect` as it carried side-effects that
-    were hardcoded/designed to use multi-selection on checkboxes. (#9391)
-    Specifically removed those undocumented behaviors from `_NoAutoSelect`:
-    - Clicking a selected/checked item always unselect/uncheck.
-    - Shift+Click inverts targets value and copy to range.
-    - Shift+Keyboard copy selection source value to range.
-    Those behaviors are still happening on checkboxes used within multi-selection.
-- Fonts:
-  - Added `IMGUI_DISABLE_DEFAULT_FONT_BITMAP`/`IMGUI_DISABLE_DEFAULT_FONT_VECTOR` to
-    disable embedding either fonts separately. (#9407)
-  - Tweak `CalcTextSize()` awkward width rounding/ceiling code to reduce floating-point
-    precision issues altering the result by 1 even at relatively small width. (#791)
-  - Better document the fact that `ImFontAtlas::Clear()`/`ClearFonts()` functions are
-    unlikely to be useful nowadays. Better recover to an edge case of mistakenly
-    calling `ClearFonts()` during rendering.
-  - Fixed an issue where passing a manually created ImFontAtlas to CreateContext() would
-    incorrectly destroy it in `DestroyContext()` when ref-count gets back to zero. (#9426)
-  - Destroying an ImGui context using a `ImFontAtlas` checks that the later has no references.
-- Nav:
-  - Fixed context menu activation with gamepad erroneously testing for _NavEnableKeyboard
-    instead of _NavEnableGamepad. (#9454, #8803, #9270) [@Clownacy]
-- TreeNode:
-  - Fixed nav cursor rendering with rounding even though tree nodes don't have it. (#7589)
-- Inputs:

-    between single-click and double-click for actions that needs single-click to do
-    something other than selection. (#8337)
-    - Returns 1 on single-click but delayed by io.MouseSingleClickDelay.
-    - Returns 2 on double-click, and 2+ on subsequent repeated clicks.
-  - Added `io.MouseSingleClickDelay` to configure default delayed single click delay when
-    using `GetItemClickedCountWithSingleClickDelay()` or `IsMouseReleasedWithDelay()`. (#8337)

------------------------------------------------------------------------
- VERSION 1.92.8 (Released 2026-05-12)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.92.8
-
-Breaking Changes:
-
-- DrawList: swapped the last two arguments of `AddRect()`, `AddPolyline()`, `PathStroke()`.
-   - Before: `void ImDrawList::AddRect(ImVec2 p_min, ImVec2 p_max, ImU32 col, float rounding = 0.0f, ImDrawFlags flags = 0, float thickness = 1.0f);`
-   - After:  `void ImDrawList::AddRect(ImVec2 p_min, ImVec2 p_max, ImU32 col, float rounding = 0.0f, float thickness = 1.0f, ImDrawFlags flags = 0);`
-   - Before: `void ImDrawList::AddPolyline(const ImVec2* points, int num_points, ImU32 col, ImDrawFlags flags, float thickness);`
-   - After:  `void ImDrawList::AddPolyline(const ImVec2* points, int num_points, ImU32 col, float thickness, ImDrawFlags flags = 0);`
-   - Before: `void ImDrawList::PathStroke(ImU32 col, ImDrawFlags flags = 0, float thickness = 1.0f);`
-   - After:  `void ImDrawList::PathStroke(ImU32 col, float thickness = 1.0f, ImDrawFlags flags = 0);`
-  Added inline redirection functions when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is off.
-  Marked the old functions are =delete when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is on, to allow for better type-checking.
-  Effectively the typical call site is changing from:
-   - Before: `window->DrawList->AddRect(p_min, p_max, color, rounding, ImDrawFlags_None, border_size);`
-   - After:  `window->DrawList->AddRect(p_min, p_max, color, rounding, border_size);`
-  Notes:
-   - Users of C++ and other languages with type-checking will be notified at compile-time of any mistakes.
-   - Users of high-level bindings or languages with no type-checking will be notified at runtime via an assert for invalid flags value.
-     If you are a binding maintainer consider doing something to facilitate transition or error detection.
-   - This is perhaps the worst breaking change in our history :( but it makes ImDrawList function signatures consistent.
-     As we are aiming to add flags and features to variety of ImDrawList functions, that consistency becomes more important.
-     The new order is also more convenient as `flags` are less frequently used than `thickness` in real code.
-   - As a general policy in Dear ImGui, all our flags default to 0 so ImDrawFlags_None was likely written 0 in some call sites.
-   - Consider adding `#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in your imconfig.h, even temporarily, to clean up legacy code.
-   - Reminder: you do NOT need to specify `ImDrawFlags_RoundCornersAll` for rounding, it is already the default!
-- DrawList: obsoleted `ImDrawCallback_ResetRenderState` in favor of using `ImGui::GetPlatformIO().DrawCallback_ResetRenderState`,
-    which is part of our new standard draw callbacks. (#9378)
-    Redirecting the earlier value into the later one when set, so both old and new code should work.
-- DrawList: changed value of `ImDrawFlags_Closed`. It was previously advertised as "always == 1" when introduced
-  in 1.82 (2021/02), in order to facilitate backward compatibility with the legacy `bool closed` flag. This
-  guarantee has been removed. The bit is reserved, and `AddPolyline()`, `PathStroke()` will assert when it is used.
-- Backends:
-  - Vulkan: redesigned to use separate ImageView + Sampler instead of Combined Image Sampler. (#914)
-    This change allows us to facilitate changing samplers, in line with other backends. [@yaz0r, @ocornut]
-    - When creating your own descriptor pool (instead of letting backend creates its own):
-      - Before: need at least `IMGUI_IMPL_VULKAN_MINIMUM_IMAGE_SAMPLER_POOL_SIZE` descriptors of type `VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER`.
-      - After:  need at least `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE` descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE`.
-                            + `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE`       descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLER`.
-    - When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler.
-      - Before: `ImGui_ImplVulkan_AddTexture(VkSampler, VkImageView, VkImageLayout)`
-      - After:  `ImGui_ImplVulkan_AddTexture(VkImageView, VkImageLayout)`
-      - Kept inline redirection function that ignores the sampler (will obsolete).
-  - DirectX10, DirectX11, SDLGPU3, Vulkan: removed samplers from `ImGui_ImplXXXX_RenderState`.
-    Prefer to use backend-agnostic DrawCallback_SetSamplerLinear which works everywhere! (#9378)
-    If there is a legit need/request for them or any render state we can always add them back.
-  - OpenGL3: the new sampler support system prioritize using glBindSampler() when available,
-    which would override glTexParameter() settings you may have set on custom textures. (#9378)
-
-Other Changes:
-
-- DrawList:
-  - Added room in `ImGuiPlatformIO` for standard backend-agnostic draw callbacks. Those callbacks
-    are setup/provided by the backend and available in most of our standard backends.
-    They allow backend-agnostic code from e.g. switching to a Nearest/Point sampler without
-    messing with custom Renderer-specific callbacks.
-      platform_io.DrawCallback_ResetRenderState;    // Request to reset the graphics/render state.
-      platform_io.DrawCallback_SetSamplerLinear;    // Request to set current texture sampling to Linear
-      platform_io.DrawCallback_SetSamplerNearest;   // Request to set current texture sampling to Nearest/Point
-    Note that some backends might not support all callbacks.
-    (#9378, #9371, #3590, #8926, #2973, #7485, #7468, #6969, #5118, #7616, #9173, #8322, #7230,
-    #5999, #6452, #5156, #7342, #7592, #7511)
-  - Made `AddCallback()` user data default to Null for convenience.
-  - Added `AddLineH()`, `AddLineV()` helpers to draw horizontal and vertical lines. [@memononen]
-    The new functions are more optimal and will be part of a larger effort in 1.93 to fix
-    inconsistencies and improve the DrawList API. In the current API, `AddLine()` adds a "magic" +0.5f
-    offset and then center the line, whereas AddLineH()/AddLineV() use the right side of the line to expand.
-    For thickness=1.0f lines this is equivalent:
-      `AddLine({10,3}, {20,3}, ...)` --> `AddLineH(x1=10, x2=20, y=3, ...)`.
-      `AddLine({3,10}, {3,20}, ...)` --> `AddLineV(x=3, y1=10, y2=20, ...)`.
-    For larger integer thickness, AddLine() will center but may be blurry, AddLineH()/AddLineV()
-    will expand "inside" (to the right side) and will always be sharp.
-    A subsequent release will expand on those concepts and add new options.
-- InputText:
-  - InputTextMultiline: fixed an issue processing deactivation logic when an active
-    multi-line edit is clipped due to being out of view.
-  - Fixed a crash when toggling ReadOnly while active. (#9354)
-  - `CharFilter` callback event sets CursorPos/SelectionStart/SelectionEnd. (#816)
-- Tables:
-  - Fixed issues reporting ideal size to parent window/container: (#9352, #7651)
-    - When both scrollbars are visible but only one of ScrollX/ScrollY was explicitly requested.
-    - When vertical scrollbar was not at the top, the computation was often incorrect.
-- Windows:
-  - Fixed a single-axis auto-resizing feedback loop issue with nested containers
-    and varying scrollbar visibility. (#9352)
-  - Detect and report error when calling End() instead of EndPopup() on a popup. (#9351)
-  - Child windows with only `ImGuiChildFlags_AutoResizeY` flag keep using the proportional
-    default `ItemWidth`. (#9355)
-  - Using mouse wheel to scroll takes and keeps ownership of the corresponding keys
-    (e.g. `ImGuiKey_MouseWheelY`) while a wheeling window is locked. (#2604, #3795)
-- InputInt, InputFloat, InputScalar:
-  - Reinstated `ImGuiInputTextFlags_EnterReturnsTrue` support which was removed in 1.91.4.
-    (#8665, #9299, #8065, #3946, #6284, #9117)
-    - Fixed the fact that it didn't return true when validating same value.
-    - Fixed losing value when tabbing out or losing focus.
-    - Made it that pressing +/- step buttons also return true, which is in line
-      with 1.91.4 behavior.
-    - In a majority of cases you should use `IsItemDeactivatedAfterEdit()` instead,
-      but it still has a few edge cases flaws (to be addressed soon).
-  - Allow passing a format string that does not display the scalar value.
-    Parsing input with default format for the type. (#9385) [@FireFox2000000]
-- Multi-Select:
-  - Fixed an issue using Multi-Select within a Table causing column width measurement to
-    be invalid when trailing column contents is not submitted in the last row. (#9341, #8250)
-  - Fixed an issue using Multi-Select within a Table with the right-most column visible,
-    which could lead to an extra vertical offset in the Header row. (#8250)
-- Multi-Select + Box-Select:
-  - Fixed an issue using `ImGuiMultiSelectFlags_BoxSelect1d` mode while scrolling.
-    Notably, using mouse wheel while holding a box-selection could lead items close to windows
-    edges from not being correctly unselected. (#7994, #8250, #7821, #7850, #7970)
-  - Improved dirty/unclip rectangle logic for `ImGuiMultiSelectFlags_BoxSelect2d`.
-  - Fixed an issue using `ImGuiMultiSelectFlags_BoxSelect2d` mode, where
-    items out of view wouldn't be properly selected while scrolling while mouse cursor
-    is hovering outside of selection scope. (#7994, #1861, #6518)
-  - Fixed an issue where items out of horizontal view would sometimes lead
-    to incorrect merging of sequential selection requests while also scrolling fast
-    enough to overlap multiple rows during a frame. (#7994, #1861, #6518)
-  - Fixed an issue using `ImGuiMultiSelectFlags_BoxSelect2d` mode in a Table
-    while relying on the `TableNextColumn()` return value to perform coarse clipping. (#7994)
-  - Disabled merging consecutive selection requests as we have no reliable
-    way of detecting if user has submitted all consecutive items without clipping gaps,
-    and `ImGuiSelectionUserData` is technically opaque storage. (#7994, #1861)
-    (we will probably bring this back as a minor optimization if we have a way to for
-    user to tell us `ImGuiSelectionUserData` are indices)
-  - Fixes for using across nested child windows. (#8364)
-  - Box-Select + Clipper: fixed an issue selecting items while scrolling while a clipper
-    active. (#7994, #8250, #7821, #7850, #7970)
-  - Box-Select + Tables: fixed an issue using box-selection in a tables with
-    items straying out of columns boundaries. (#7994, #2221)
-  - Box-Select + Tables: fixed an issue when calling `BeginMultiSelect()` in a table
-    before layout has been locked (first row or headers row submitted). (#8250)
-- Menus:
-  - BeginMenu()/MenuItem(): fixed accidental triggering of child menu items when
-    opening a menu inside a small host window forcing the child menu window to be
-    repositioned under the mouse cursor. (#8233, #9394)
-    Done by reworking `BeginMenu()`/`MenuItem()`: they previously avoiding taking
-    ActiveID + key/click ownership (in order to allow releasing button on another item).
-    Now they take them and release them once the mouse is moved outside item boundaries.
-- Inputs:
-  - SetItemKeyOwner(): return true if ownership has been requested, which typically
-    needs to to checked for gating further tests. This is important as the function
-    may fail. (#456, #2637, #2620, #2891, #3370, #3724, #4828, #5108, #5242, #5641)
-  - SetItemKeyOwner(): does not set ownership is key is already taken. Effectively
-    this makes using `SetItemKeyOwner(ImGuiKey_MouseWheelY)` over an item work as
-    expected while not having item react if a scroll wheel is actively in progress.
-    May be subject to further redesign, e.g. conditional flags. Feedback welcome!
-- Style:
-  - Checkbox: added `ImGuiCol_CheckboxSelectedBg` to change or accentuate the
-    background color of checked/mixed checkboxes. (#9392)
-  - Added `ImGuiStyleVar_DragDropTargetRounding`. (#9056)
-  - Fixed vertical scrollbar top coordinates when using thick borders on windows
-    with no title bar and no menu bar. (#9366)
-- Fonts:
-  - imgui_freetype: add FreeType headers & compiled version in 'About Dear ImGui' details.
-  - Assert when using MergeMode with an explicit size over a target font with an implicit
-    size, as scale factor are likely erroneous. (#9361)
-- Clipper:
-  - Improved error reporting when misusing the clipper inside a table (prioritize
-    reporting the common clipper error over a table sanity check assert). (#9350)
-  - Tweaked assert triggering when first item height measurement fails, and made it
-    a better recoverable error. (#9350)
-- Misc:
-  - Minor optimization: reduce redundant label scanning in common widgets.
-  - Added missing Test Engine hooks for `PlotLines()`, `PlotHistogram()`, `VSliderXXX()`
-    and `TableHeader()` functions.
-- Demo:
-  - Added simple demo for a scrollable/zoomable image viewer with a grid.
-    Available in `Examples->Image Viewer` and `Widgets->Images`.
-- Backends:
-  - Added support for new standardized draw callbacks in most backends: (#9378)
-    - Allegro5:     Reset     n/a               n/a
-    - DX9:          Reset     SetSamplerLinear  SetSamplerNearest
-    - DX10:         Reset     SetSamplerLinear  SetSamplerNearest
-    - DX11:         Reset     SetSamplerLinear  SetSamplerNearest
-    - DX12:         Reset     SetSamplerLinear  SetSamplerNearest
-    - Metal:        Reset     SetSamplerLinear  SetSamplerNearest
-    - OpenGL2:      Reset     SetSamplerLinear  SetSamplerNearest
-    - OpenGL3+:     Reset     SetSamplerLinear  SetSamplerNearest
-    - SDLGPU3:      Reset     SetSamplerLinear  SetSamplerNearest
-    - SDLRenderer2: Reset     n/a               n/a
-    - SDLRenderer3: Reset     SetSamplerLinear  SetSamplerNearest
-    - Vulkan:       Reset     SetSamplerLinear  SetSamplerNearest
-    - WebGPU:       Reset     SetSamplerLinear  SetSamplerNearest
-    (Vulkan backend by @yaz0r, Metal by @ssh4net, others by @ocornut)
-  - GLFW: added a Win32-specific implementation of `ImGui_ImplGlfw_GetContentScaleXXXX`
-    functions for legacy GLFW 3.2. (#9003)
-  - Metal: avoid redundant vertex buffer bind in `SetupRenderState()`, which leads
-    to validation issue. (#9343) [@Hunam6]
-  - Metal: use a dedicated `bufferCacheLock` to avoid crashing when `bufferCache` is
-    replaced by a new object while being used for `@synchronize()`. (#9367) [@andygrundman]
-  - SDL2: made `ImGui_ImplSDL2_GetContentScaleForWindow()`/`ImGui_ImplSDL2_GetContentScaleForDisplay()`
-    helpers return a minimum of 1.0f, as some Linux setup seems to report <1.0f value
-    and this breaks scaling border size. (#9369)
-  - WebGPU: rework choice/detection of using WGSL/SPIR-V shader on WGVK. (#9316, #9246, #9257, #9387)
-- Examples:
-  - Update VS toolset in all .vcxproj from VS2015 (v140) to VS2017 (v141). The later is the
-    first that supports vcpkg. Onward we will likely stop testing building the library with VS2015.
-  - GLFW+Vulkan, SDL2+Vulkan, SDL3+Vulkan, Win32+Vulkan: reworked to create a descriptor pool with:
-    - `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE` descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE`.
-    - `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE`       descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLER`.

 ### Q: How can I interact with standard C++ types (such as std::string and std::vector)?
-
 - Being highly portable (backends/bindings for several languages, frameworks, programming styles, obscure or older platforms/compilers), and aiming for compatibility & performance suitable for every modern real-time game engine, Dear ImGui does not use any of std C++ types. We use raw types (e.g. char* instead of std::string) because they adapt to more use cases.
 - To use ImGui::InputText() with a std::string or any resizable string class, see [misc/cpp/imgui_stdlib.h](https://github.com/ocornut/imgui/blob/master/misc/cpp/imgui_stdlib.h).

-### About Multi-Threading
-
-A same Dear ImGui context may be not used from multiple threads in parallel.
-
-If you want to use a same context within parallel tasks for occasional debug purpose, consider using a lock.
-
-If you want to submit contents from a main/update thread but render Dear ImGui output in a dedicated render thread, you'll need to stage `ImDrawData` and texture requests. See the `ImDrawDataSnapshot` and `ImTextureQueue` helpers in [imgui_threaded_rendering](https://github.com/ocornut/imgui_club#imgui_threaded_rendering). Also see topics with [label: multi-threading](https://github.com/ocornut/imgui/issues?q=label%3Amulti-threading).
-
-If you use multiple Dear ImGui contexts and want to use them from multiple threads, you need to `#define GImGui` to become a TLS variable (see details near the definition of `GImGui`. If you need to display multiple contexts simultaneously, consider using [imgui_multicontext_compositor](https://github.com/ocornut/imgui_club#imgui_multicontext_compositor). Also see topics with [label: multi-contexts](https://github.com/ocornut/imgui/issues?q=label%3Amulti-contexts).

-There is a script/patch to make the API take an explicit context pointer: [#5856](https://github.com/ocornut/imgui/pull/5856). It is presently unmaintained and likely to easy to update. It has been decided that the change is not currently worth applying to main-line but maybe will be in a future version.

-### (5) Reduce texture resizes/copy on startup
-
-🆕 Since 1.92, the ImFontAtlas is initially created using a 512x128 texture, then grows as glyphs and fonts are used. Atlas growth leads to alloc+copy, and both the old and new sized textures are present in memory for a short time (typically one frame). If you use known fonts and want to reduce initial growth, you may set `TexMinWidth` and `TexMinHeight` during initializaton.

 v1.92 introduces a newer, dynamic font system. It requires backend to support the `ImGuiBackendFlags_HasTextures` feature:
 - Users of icons, Asian and non-English languages do not need to pre-build all glyphs ahead of time. Saving on loading time, memory, and also reducing issues with missing glyphs. Specifying glyph ranges is not needed anymore.

+- `PushFont(NULL, new_size)` may be used anytime to change font size.
 - Packing custom rectangles is more convenient as pixels may be written to immediately.
 - Any update to fonts previously required backend specific calls to re-upload the texture, and said calls were not portable across backends. It is now possible to scale fonts etc. in a way that doesn't require you to make backend-specific calls.

-# Security Policy
-
-Dear ImGui is primarily designed for developer tools and technical applications running trusted code and trusted data. 
-
-Given that the library was not designed as a hardened security boundary against hostile or intentionally malformed inputs: 
-consider not using it in a context where a crash (through e.g. intentionally malformed inputs) could lead to privilege elevation. 
-E.g. running in a privileged process and interacting with non-privileged clients feeding code or data to Dear ImGui.
-
-Dear ImGui development efforts are focused on improving developer experience, usability, correctness, and robustness in real-world applications. 
-We will do our best to reduce e.g. crashes caused by common programmer mistakes.
-
-However, the project does not specifically focus on adversarial fuzzing scenarios, allocation-failure hardening, or highly artificial edge cases that are unlikely to occur in normal usage.
-
-## Reporting a Vulnerability
-
-Considering the above policy, most things may be reported in GitHub Issues.
-If you have a reason to disclose privately, please reach out to the contact address listed in README.

-# iOS / OSX Metal4 example

-## Introduction
-
-This example shows how to integrate Dear ImGui with Metal4. It is based on the "cross-platform" game template provided with Xcode as of Xcode 9.
-
-Consider basing your work off the example_glfw_metal/ or example_sdl2_metal/ examples. They are better supported and will be portable unlike this one.

-- `imgui_impl_qnx.cpp` as the QNX Screen platform backend
-- `imgui_impl_opengl3.cpp` as the renderer backend
-- EGL to create an OpenGL ES 3 context and Screen window surface
-
-`imgui_impl_opengl3.cpp` supports desktop OpenGL and OpenGL ES. On QNX this
-example compiles it with `IMGUI_IMPL_OPENGL_ES3` and uses `#version 300 es`.
-No separate Screen/OpenGL renderer backend is required.
-
-## Build
-
-Load the QNX SDP environment, then run:
-
-```sh
-cd examples/example_qnx_opengl3
-make
-```
-
-The QNX recursive make files build for the CPUs enabled in your SDP
-configuration and install the program as `example_qnx_opengl3`.
-
-## Input
-
-The application polls its `screen_context_t` event queue and forwards every
-non-`SCREEN_EVENT_NONE` event to `ImGui_ImplQNX_ProcessEvent()`.
-Escape exits the example.

-# Dear ImGui QNX Screen + Vulkan example
-
-This example uses:
-
-- `imgui_impl_qnx.cpp` as the QNX Screen platform backend
-- the unmodified `imgui_impl_vulkan.cpp` renderer backend
-- `vkCreateScreenSurfaceQNX()` and `VK_QNX_screen_surface`
-
-No separate Screen/Vulkan renderer backend is required. The QNX-specific work
-is limited to the Screen platform backend, native window setup, and Vulkan WSI
-surface creation.
-
-## Build
-
-Load the QNX SDP environment, then run:
-
-```sh
-cd examples/example_qnx_vulkan
-make
-```
-
-The build defines `VK_USE_PLATFORM_SCREEN_QNX` and links `libvulkan` and
-`libscreen`.
-
-## Input and resize
-
-The application forwards Screen input events to `ImGui_ImplQNX_ProcessEvent()`.
-It recreates the Vulkan swapchain when the Screen window size changes or Vulkan
-reports `VK_ERROR_OUT_OF_DATE_KHR` / `VK_SUBOPTIMAL_KHR`. Escape exits.
