403 * Note for d3d8 and d3d9:
404 * The vertex buffer FVF doesn't help with finding them, we have to use
405 * the decoded vertex declaration and pick the things that concern the
406 * current buffer. A problem with this is that this can change between
407 * draws, so we have to validate the information and reprocess the buffer
408 * if it changes, and avoid false positives for performance reasons.
409 * WineD3D doesn't even know the vertex buffer any more, it is managed

411 * as needed.
413 * We have to distinguish between vertex shaders and fixed function to
414 * pick the way we access the strided vertex information.
416 * This code sets up a per-byte array with the size of the detected
417 * stride of the arrays in the buffer. For each byte we have a field
418 * that marks the conversion needed on this byte. For example, the

421 * POSITIONT, FLOAT4
422 * NORMAL, FLOAT3
423 * DIFFUSE, FLOAT16_4
424 * SPECULAR, D3DCOLOR
426 * Will result in

428 * [P][P][P][P][P][P][P][P][P][P][P][P][P][P][P][P][0][0][0][0][0][0][0][0][0][0][0][0][F][F][F][F][F][F][F][F][C][C][C][C]
430 * Where in this example map P means 4 component position conversion, 0
431 * means no conversion, F means FLOAT16_2 conversion and C means D3DCOLOR
432 * conversion (red / blue swizzle).
434 * If we're doing conversion and the stride changes we have to reconvert
435 * the whole buffer. Note that we do not mind if the semantic changes,
436 * we only care for the conversion type. So if the NORMAL is replaced
437 * with a TEXCOORD, nothing has to be done, or if the DIFFUSE is replaced
438 * with a D3DCOLOR BLENDWEIGHT we can happily dismiss the change. Some
439 * conversion types depend on the semantic as well, for example a FLOAT4
440 * texcoord needs no conversion while a FLOAT4 positiont needs one
