- 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
- 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
- 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
- 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)
- 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
- Use inline array + AddPolyline/AddConvexPolyFilled for triangle and quad
- do less computation for detecting small shape rendering
- add IM_UNLIKELY for very unlikely branches
- changed truncated tests to use macro, and inline the computation in debug builds (~15% was spent on calling the functions)
- inlined the common rectangle cases in AddRect() for debug build speed up
- fixed how super sampled line textures are generated (and documented wrong assumption)
- switched to more samples and smaller thickness range
- tweaked super sampled texture selection to hide the texture changed better
- added animated thickness to demo to make it easier to evaluate thickness visual progression
- added super sampled textures in thickness range [1..3] to avoid visual pop
- 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 generic stroke position to all path rendering
- removed stroke folding in favor of limiting the miter width (simplifies the geometry cases)
- removed fractional stroke rendering in favor of using the integer sized rendering for everything
- the rationale is that the in-between sizes are a bit blurry anyways, and the error we get from scaling is visually acceptable
- added stroke position option for the demo
- updated the degenerate shape handling
- remove AddLine() stroke pos handling
- removed up commented out code.
- Added square cap rendering to the DrawPolyline, which can be turned on by ImDrawFlags_SquareCap
- Added draw flags to AddBezierCubic() and AddBezierQuadratic()
- add bevel handling for sharp corners
- add limit to the miter distance to avoid inner shape spikes
- add support for ImDrawFlags_MiterOnly to keep well behaved rendering fast
