+// 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).
+//  [ ] Platform: Multi-viewport support.
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+//  2026-08-04: Initial QNX Screen backend. (#9492)

+// 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.

+-----------------------------------------------------------------------
+
+Breaking Changes:
+
+Autumn cleanup of stuff marked obsolete more than two years ago:
+
+- Commented out legacy names/functions which were obsoleted in 1.90.7 (May 2024);

+- Please also try to get rid of calls to `GetContentRegionMax()`, `GetWindowContentRegionMin()`
+  and `GetWindowContentRegionMax()` will may be removed soon-ish: you should not
+  ever need those functions. See #7838.
+
+
+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.

+    (if you have a problem to discuss, please open a new issue)
+
+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:

+    - 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).

 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.
+- `PushFont(nullptr, 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.
 - It is possible to plug a custom loader/backend to any font source.

+- `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.
