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%.
