/* Where do we get our vertex data?
 *
 * Vertex data either comes either from immediate mode registers or from
 * vertex arrays.
 * There appears to be no mixed mode (though we can force the pitch of
 * vertex arrays to 0, effectively reusing the same element over and over
 * again).
 *
 * Immediate mode is controlled by the INPUT_CNTL registers. I am not sure
 * if these registers influence vertex array processing.
 *
 * 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.

/* BEGIN: Upload vertex program and data */

/*
 * The programmable vertex shader unit has a memory bank of unknown size
 * that can be written to in 16 byte units by writing the address into
 * UPLOAD_ADDRESS, followed by data in UPLOAD_DATA (multiples of 4 DWORDs).
 *
 * Pointers into the memory bank are always in multiples of 16 bytes.
 *
 * The memory bank is divided into areas with fixed meaning.
 *
 * Starting at address UPLOAD_PROGRAM: Vertex program instructions.
 * Native limits reported by drivers from ATI suggest size 256 (i.e. 4KB),
 * whereas the difference between known addresses suggests size 512.
 *
 * Starting at address UPLOAD_PARAMETERS: Vertex program parameters.
 * Native reported limits and the VPI layout suggest size 256, whereas
 * difference between known addresses suggests size 512.
 *
 * At address UPLOAD_POINTSIZE is a vector (0, 0, ps, 0), where ps is the
 * floating point pointsize. The exact purpose of this state is uncertain,
 * as there is also the R300_RE_POINTSIZE register.
 *
 * Multiple vertex programs and parameter sets can be loaded at once,
 * which could explain the size discrepancy.
