- added ImDrawFlags_StrokeCenterPixelAligned which center aligns stroke so that outside of the stroke is pixel aligned
- fixed AddRect() non-rounded pixel aligned case to use correnct min/max
- fixed AddRect() default case to not adjust rounding for non-rounded rects
- fixed lineV() centered offset
- renamed ImDrawFlags_StrokeCenterPixelAligned to ImDrawFlags_StrokeCenterAligned.
- reduced debug build indirections.
- added ImFontAtlasFlags_NoBakedRoundCorners which controls if rounded corners should be baked to texture
- added ImDrawListFlags_RoundCornersUseTex which controls if we should try to use textured roudned corners
- fixed how _FringeScaleIsInteger is calculated (we want to detect integer pixel scale)
- fixed how _FringeScale is used with textured rounded corners
- added check to render simpler geometry when (stroked) rectangle has integer coords
- render non.rounded with 4 non-AA rectangles
- added textures for corners of 1-3 thickness and 1-16 rounding
- use textured corners when possible, or fallback to generic one
- removed half pixel offset from ImDrawList::AddLine()
- added ImDrawList::AddHorizontalLine() and ImDrawList::AddVerticalLine() which draw line to the side of the specified line
- Change uses of AddLine() which were obviously vertical and horizontal to use the v and h lines
- Fixed layouting issues from above changes
- Changed primitives demo to use vline and hline
- Fixed angled header to match original
- Fixed separator line to match original
- Fixed caret to match original
- Fix separator vertical alignment
- Added stroke pos, which controls how stroke is draw relative to the shape
- Kept legacy mode which does 1/2px inset
- Added stroke pos support for Rect, Circle, Ngon, and Ellipse
- add stroke pos to hline and vline
- Added drawflag ImDrawFlags_TruncateCoords which allows to hint the renderer that the input is snapped to pixels (can disable AA in some cases)
- Implemented 9-slice renderer for rounded corners
- Remove ImDrawFlags_TruncateCoords flag in favor of detecting truncated coords.
- Renamed to AddLineH(), AddLineV()
- Removed ImDrawStrokePos, folded into ImDrawFlags
The main fix is the change from GetColorU32() to ColorConvertFloat4ToU32() in calling code.
The change from GetColorU32() to manual multiply in RenderColorRectWithAlphaCheckerboard() is merely for consistency with other ::Render calls.
Using a FrameCount for compare. Kept time as float to be consistent with other GC-related timestamps: if there is an actual need to use double we'll switch everywhere.
Was possibly harmless because DpiScale is only used by user or certain opt-in feature.
But, Metal backend wrongly used viewport->DpiScale in ImGui_ImplMetal_SetWindowSize() so it might affect it cc #6828
