 *
 * 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.
 *
 * Always set COMPONENTS_4 in immediate mode.
