- * Triangle Rasterizer Template
- *
- * This file is #include'd to generate custom triangle rasterizers.
- *
- * The following macros may be defined to indicate what auxillary information
- * must be interplated across the triangle:
- * INTERP_Z - if defined, interpolate Z values
- * INTERP_RGB - if defined, interpolate RGB values
- *
- * TAG - function name
- * CULL - enable culling for: 0=no, 1=back, -1=front
- *
- * SETUP_CODE - to be executed once per triangle (usually HW init)
- *
- * For flatshaded primitives, the provoking vertex is the final one.
- * This code was designed for the origin to be in the upper-left corner.
- *
- * Inspired by triangle rasterizer code written by Brian Paul.
