c4eab3f44f DrawList: fixed PathArcTo to not emit small segments. 
- Changed PathArcTo to select start/end sample in quatized multiples of arc fast sample count
- This is done in order to avoid small segments at the start and end of the path, which causes issues with line AA ends
- Renamed CalcArcStepAndCount to CalcCornerArcStepAndCount to make it more clear that it returns the values for 90 degree arc

5886eae83d DrawList: fixed too many detailed line textures being created. 
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.

45ff8bdde6 DrawList: fixed rendering issues on small and degenerate shapes. 
The "does stroke cover the whole shape" used to be overly pessimistic to stroking artifacts. This was due to the fringe, where the geometry would mess up before visually closing the shape.
Fixed the issue by adding max inner offest for the AddPolyline(), which limits the inner offset and also adjusts the texture coords.
Second part of the fix was to calculate the pass the max inner offset from the common shapes (circle, ngon, ellipse, rect).
While this does not fix all the ellipse rendering issues, it limits the issue a lot.
e.g. AddRect() w/ size=5, thickness=2 used to trigger AddRectFilled() fallback because threshold was pessimistic to prevent the AddPolyline() issues.

a58770dcf8 DrawList: fixed overdraw issue for filled baked corner rendering. 
Require all corners to fit inside the rect to avoid overdraw (or fallback to path rendering).
eg. AddRectFilled() w/ size=10, rounding=8 or 10 would break.

26647360b3 DrawList: fixed filled rect baked AA. 
Always add 1px to the fill side of the rounded corner to prevent the corner AA to bleed into the rectangle edges.

712f2bd67d TabBar: simpify TabItem rendering using stroke flags. 
May tend toward using _StrokeInside more but _StrokeCenterBiased is closer to current behavior.

f57df5e380 DrawList: consistently support scope flags (ImDrawFlags::Flags) + primitive flags. 
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)

3879c2861b DrawList: Optimize AddNgon() 
- test overestimate before testing more expensive details when testing if stroked ngon is actualy filled
- Note: not a common function, but the test harness is using this to draw a triangle, which makes it show up in profiling

f67467e17b DrawList: Revert texture selection to simple round() in _SelectFringeTexture 
- revert texture selection to use just (inlined) round()
- the values were tuned to hide texture selection pops on small thickness
- since we're using super sampling for the problematic range, the tweaks are not necessayr anymore
