Description

Thanks for all the work on this. I'm currently using it as a basis for a data viz focused rendering pipeline.

Allowing mesh rendering would greatly expand the power of Vello for e.g. rendering paths with variable width/stroke color etc. I'm currently battling with getting rid of AA seams when rendering the triangles individually.

Research direction

Start by reviewing Vello's existing rendering pipeline and the issue's requirements for mesh geometry and per-vertex colors. Determine how the proposed support should handle rendering paths with variable width or stroke color and avoid antialiasing seams. Done means meshes render with per-vertex color as described, with coverage for the relevant behavior.
