*
* Vertex arrays are controlled via the 3D_LOAD_VBPNTR packet3.
*
* In both cases, vertex attributes are then passed through INPUT_ROUTE.
*
* Beginning with INPUT_ROUTE_0_0 is a list of WORDs that route vertex data
* into the vertex processor's input registers.
* The first word routes the first input, the second word the second, etc.
* The corresponding input is routed into the register with the given index.
* The list is ended by a word with INPUT_ROUTE_END set.
