382 * A rectangle primitive (3DPRIM_RECTLIST) consists of only three

384 * coordinates (that is, (0, 0) is the upper left corner).
391 * Since the VS is disabled, the clipper loads each VUE directly from
392 * the URB. This is controlled by the 3DSTATE_VERTEX_BUFFERS and
393 * 3DSTATE_VERTEX_ELEMENTS packets below. The VUE contents are as follows:
394 * dw0: Reserved, MBZ.
395 * dw1: Render Target Array Index. Below vertex fetcher gets programmed
396 * to assign this with primitive instance identifier which will be
397 * used for layered clears. All other renders have only one instance
398 * and therefore the value will be effectively zero.
399 * dw2: Viewport Index. The HiZ op disables viewport mapping and
400 * scissoring, so set the dword to 0.
401 * dw3: Point Width: The HiZ op does not emit the POINTLIST primitive,
402 * so set the dword to 0.
403 * dw4: Vertex Position X.
404 * dw5: Vertex Position Y.
405 * dw6: Vertex Position Z.
406 * dw7: Vertex Position W.
408 * dw8: Flat vertex input 0
409 * dw9: Flat vertex input 1
411 * dwn: Flat vertex input n - 8
413 * For details, see the Sandybridge PRM, Volume 2, Part 1, Section 1.5.1
414 * "Vertex URB Entry (VUE) Formats".
416 * Only vertex position X and Y are going to be variable, Z is fixed to
417 * zero and W to one. Header words dw0,2,3 are zero. There is no need to
418 * include the fixed values in the vertex buffer. Vertex fetcher can be
419 * instructed to fill vertex elements with constant values of one and zero
420 * instead of reading them from the buffer.
421 * Flat inputs are program constants that are not interpolated. Moreover
422 * their values will be the same between vertices.
