Patrick Walton	5879d9778d	Replace the MCAA shader with an extended Loop-Blinn approach and an approximation of area based on approximate first-order line distance. This enables support for full affine transforms in MCAA. It also greatly simplifies the shader and reduces the amount of work that the GPU needs to do for fragment shading. Experimental testing has shown the area approximation to be accurate to about 4%.	2018-02-02 18:28:41 -08:00
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

Replace the MCAA shader with an extended Loop-Blinn approach and an

approximation of area based on approximate first-order line distance.

This enables support for full affine transforms in MCAA. It also greatly
simplifies the shader and reduces the amount of work that the GPU needs
to do for fragment shading.

Experimental testing has shown the area approximation to be accurate to
about 4%.
