  2. 	/* TODO

  3. 	 *

  4. 	 * 1) It would be nice if load/store double could be used

  5. 	 *    at least for the matrix parts.  I think for the matrices

  6. 	 *    it is safe, but for the vertices it probably is not due to

  7. 	 *    things like glInterleavedArrays etc.

  8. 	 *

  9. 	 *    UPDATE: Trying this now in sparc_matrix.h -DaveM_990624

  10. 	 *

  11. 	 * 2) One extremely slick trick would be if we could enclose

  12. 	 *    groups of xform calls on the same vertices such that

  13. 	 *    we just load the matrix into f16-->f31 before the calls

  14. 	 *    and then we would not have to do them here.  This may be

  15. 	 *    tricky and not much of a gain though.
