- *    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.
