- 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
Inverting the pattern means that for our typical 3x3 grid we don't need to draw 1+4 rounded rectangles, only 1.
This also fix the slightly rounding mismatch when switching from a=255 to a<255 paths.
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.
The aim is to be able to use/add flags to more ImDrawList functions, and making existing functions consistents was deemed very desirable.
