b5ef1d837d DrawList: Comments. Atlas's NoBakedLines automatically disable AA at Style level. Fix passing non-Legacy stroke mask to PushDrawFlag(). Demo: Custom Rendering: use LiveEdit everywhere. 2026-08-06 18:12:07 +02:00

1c71e07fa0 TabBar: simpify TabItem rendering using stroke flags. 
May tend toward using _StrokeInside more but _StrokeCenterBiased is closer to current behavior.

9aec6df4fd Checkbox, Menus: check marks use anti-aliased ends. 
Currently not a satisfying resolution.

b67ced86c0 DrawList: support altering RoundCorners flags in scope as an undocumented trick/hack. (9489) 
Not documented because it could become troublesome if treated as a guaranteed styling feature.

59014d15e7 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)

b35777c58d 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

c8867c72dc DrawList: Optimize AddRectFilled() 
- detect and draw non-rounded non-AA rect with less branches and calculations
- improves new AddRectFilled() overhead from 30% to 5-10%

9549b6ff7e DrawList: Optimize _SelectFringeTexture() 
- store inverse line thickness in the spare texture uv component (same v was stord twice) to avoid division in _SelectFringeTexture

21930ad65c 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

4da24b1283 DrawList: merged _AddPolyline back into AddPolyline. 
- AddPolyline used to call different versions of _AddPolyline, the separation is not needed anymore, one less function call in debug mode

c4350c537e DrawList: removed vertex offset overflow (for 16-bit ImDrawIdx support) handling. 
This seems unnecessary for now.

34fdedfc53 DrawList: restored non-AA rendering mode. 
- 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

589c83aab9 DrawList: fixed overdraw of transparent rounded rectangles 
- transition earlier to _AddRectTinyRounding() to avoid overdraw issues

7a717a297c DrawList: fixed baked corners to better match polyline corners 
- added CalcArcStepAndCount() to calculate the step size consistently
- _AddRectTinyRounding: fixed stem placement with thin lines (clamping was needed for an older version of the function)
- _AddRectTinyRounding: fixed texture coordinates (uses if inner/outer were reversed)
- use polygon instead of circle when calculating baked corner rounds (the circle was more accurate but looked different size comparet to polyline)

475c5dadcd DrawList: added macro to have consistent check for rounding 
- use macro to test if rounding value is worthy
- changed threshold to be a bit smaller (for smoother handling of small radius), and relative to fringe
