/* Only used for texture coordinates.
 * Use the source field to route texture coordinate input from the
 * vertex program to the desired interpolator. Note that the source
 * field is relative to the outputs the vertex program *actually*
 * writes. If a vertex program only writes texcoord[1], this will
 * be source index 0.
 * Set INTERP_USED on all interpolators that produce data used by
 * the fragment program. INTERP_USED looks like a swizzling mask,
 * but I haven't seen it used that way.

 * Note: The _UNKNOWN constants are always set in their respective
