338 * Note for d3d8 and d3d9:
339 * The vertex buffer FVF doesn't help with finding them, we have to use
340 * the decoded vertex declaration and pick the things that concern the
341 * current buffer. A problem with this is that this can change between
342 * draws, so we have to validate the information and reprocess the buffer
343 * if it changes, and avoid false positives for performance reasons.
344 * WineD3D doesn't even know the vertex buffer any more, it is managed
345 * by the client libraries and passed to SetStreamSource and ProcessVertices
348 * We have to distinguish between vertex shaders and fixed function to
349 * pick the way we access the strided vertex information.
351 * This code sets up a per-byte array with the size of the detected
352 * stride of the arrays in the buffer. For each byte we have a field
353 * that marks the conversion needed on this byte. For example, the
354 * following declaration with fixed function vertex processing:
362 * { POSITIONT }{ NORMAL }{ DIFFUSE }{SPECULAR }
363 * [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]
365 * Where in this example map P means 4 component position conversion, 0
366 * means no conversion, F means FLOAT16_2 conversion and C means D3DCOLOR
367 * conversion (red / blue swizzle).
369 * If we're doing conversion and the stride changes we have to reconvert
370 * the whole buffer. Note that we do not mind if the semantic changes,
371 * we only care for the conversion type. So if the NORMAL is replaced
372 * with a TEXCOORD, nothing has to be done, or if the DIFFUSE is replaced
373 * with a D3DCOLOR BLENDWEIGHT we can happily dismiss the change. Some
374 * conversion types depend on the semantic as well, for example a FLOAT4
375 * texcoord needs no conversion while a FLOAT4 positiont needs one
