* Screenspace AA tessellated GPU path rendering.Gravatar senorblanco2016-08-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an approach to antialiased concave path rendering on the GPU without using MSAA. It uses GrTessellator to extract boundary contours from the given path, then inflates by half a pixel in screen space each direction, then renders the result with zero alpha on the outer contour and one alpha on in the inner contour. This requires two passes through the tessellation code: one to extract the boundaries, then one to tessellate the result. This gives approximately a 3X improvement on the IE chalkboard demo in non-MSAA mode, a 30-40% improvement on MotionMark's "Fill Paths", and a ~3X improvement on MotionMark's "canvas arcTo segments". It works best for large, simple paths, so there's currently a limit of 10 verbs in the onCanDrawPath() check. This dovetails nicely with the distance field path renderer's support for small, detailed (and cached) paths.

In addition, NVPR makes this very complicated, and I haven't quite figured out a good way to handle it, so for now color and coverage DO live on optstate, but I will figure out some way to refactor that in future CLs.
