Fixed issue where were creating detailed line textures up to detailed witdh + 1
Changed IM_DRAWLIST_TEX_LINES_DETAILED_WIDTH_MAX to IM_DRAWLIST_TEX_LINES_DETAILED_WIDTH_COUNT which no accounts for all the detailed line textures.
ImDrawFlags_AAEnds and ImDrawFlags_StrokeLegacy ok. (the most important ones).
ImDrawFlags_UseTexForRoundCorners ok.
ImDrawFlags_AAFill, ImDrawFlags_AAStrokes: for primitives: only for selected ones taking flags params. Haven't added the flag to all functions because it feels like a fringe use case.
ImDrawFlags_TextNoPixelSnap supported in RenderText(), per-prim (9417)
- fixed bug where fringe size was not properly applied in _AddRectTinyRounding
- optimized _AddRectTinyRounding to use less vertices
- changed _AddRectTinyRounding to use similar texturing logic as lines
- remove unused fractional line width texture
- added ImRsqrtPrecise() which adds Newton-Raphson iteration for more precision
- change calculation of miter_scale_factor so that it does not have a branch
- renamed IM_POLYLINE_APPEND_* macros to IM_APPEND_* and also use them in fill convex poly
- changed the convex poly miter calculation to match the polyline to make debugging and changes easier
- split the convex poly to separate loop when ImDrawFlags_MiterOnly is specified for less branches in common case
# Conflicts:
# imgui_draw.cpp
- 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
