Didn't convert Combo() "const char* items_separated_by_zeros" as this doesn't translate well when used via a ImStrv constructor, may actually aim to obsolete.
Fixed for shadowing local variable warning on 2025/06/25.
Squashed commits (initially a commit from rokups + many rework by ocornut. keeping them separate commits made rebasing unnecessarily tricking so merged from 2024/02)
ImStrv: many fixes (see details), added imconfig class extension example, added natvis description.
ImStrv: rework toward ensuring End is always set to constant can be compile time calculated
ImStrv: using length(), fix ambiguous empty() function, fix altered behaviors, removed unused operators.
ImStrv: various tweaks and fixes. removed ImGuiTextRange from ImGuiTextFilter, fix test engine hooks, removed constructor only used twice.
- the ImDrawListFlags_AntiAliasedFill and ImDrawListFlags_AntiAliasedLines flags work again
- added non-AA rendering for polyline and convex poly filled
- do not use corner textures when AA is not used
- Add missing no-AA for single line case
- changed truncated tests to use macro, and inline the computation in debug builds (~15% was spent on calling the functions)
- inlined the common rectangle cases in AddRect() for debug build speed up
- added animated thickness to demo to make it easier to evaluate thickness visual progression
- added super sampled textures in thickness range [1..3] to avoid visual pop
- added generic stroke position to all path rendering
- removed stroke folding in favor of limiting the miter width (simplifies the geometry cases)
- removed fractional stroke rendering in favor of using the integer sized rendering for everything
- the rationale is that the in-between sizes are a bit blurry anyways, and the error we get from scaling is visually acceptable
- added stroke position option for the demo
- updated the degenerate shape handling
- remove AddLine() stroke pos handling
- removed up commented out code.
- Added square cap rendering to the DrawPolyline, which can be turned on by ImDrawFlags_SquareCap
- Added draw flags to AddBezierCubic() and AddBezierQuadratic()
- Add ImDrawFlags_MiterOnly which is used to indicate that a path contains simple geometry and can be rendered using mitered corners
- Added handling of degenerated shapes for stroked rectangle, circle, ngon, and ellipse
- Render shapes filled when outline covers the whole shape
- Clamp very small circles and ngons, and use alpha fade below one pixel
- Added correct offset for ellipse
- added 2 variants of polyline rendering
- one handles integer-sized thickness using one strip of triangles along the line
- second handles any thickness using 2 strips of triangles long the line
- changed vertical AddLine() to be consistent with AddLineV()
- changed CenterPixelAligned growth to be smoother
- added (temporary) specialized stroke pos support for AddLine()
