Draw list 1.93 strokes: _AddPolyline ported (texture AA lines, joins/miter/bevel, CapSquare, AALineEnds, Stroke Inside/Center/CenterBiased/Outside/Legacy), AddConvexPolyFilled AAFill, all primitives with 1.93 signatures/flags, PathRect/PathArcTo 1.93, baked line textures; Custom Rendering demo flags UI restored. check_all: t_pixels incremental==full redraw, headless screenshot (tools/test/shot.py)
