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