Patrick Walton	6a640eca74	Simplify the B-quad vertex position VBO to have a uniform format, and ... enable early Z for SVG. Additionally, this switches the B-quad patches for XCAA to be convex hulls instead of bounding boxes, reducing fragment shader load. This is a large speedup for the Ghostscript tiger demo: 5x or more. Closes #33.	2018-01-11 19:25:02 -08:00
