3 /* TODO
4 *
5 * 1) It would be nice if load/store double could be used
6 * at least for the matrix parts. I think for the matrices
7 * it is safe, but for the vertices it probably is not due to
8 * things like glInterleavedArrays etc.
9 *
10 * UPDATE: Trying this now in sparc_matrix.h -DaveM_990624
11 *
12 * 2) One extremely slick trick would be if we could enclose
13 * groups of xform calls on the same vertices such that
14 * we just load the matrix into f16-->f31 before the calls
15 * and then we would not have to do them here. This may be
16 * tricky and not much of a gain though.
