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.
