/* Special handling for color: When the fragment program uses color,
* the ROUTE_0_COLOR bit is set and ROUTE_0_COLOR_DEST contains the
* color register index.
*
* Apperently you may set the R300_RS_ROUTE_0_COLOR bit, but not provide any
* R300_RS_ROUTE_0_COLOR_DEST value; this setup is used for clearing the state.
* See r300_ioctl.c:r300EmitClearState. I'm not sure if this setup is strictly
* correct or not. - Oliver.
