424 * Note for d3d8 and d3d9:
425 * The vertex buffer FVF doesn't help with finding them, we have to use
426 * the decoded vertex declaration and pick the things that concern the
427 * current buffer. A problem with this is that this can change between
428 * draws, so we have to validate the information and reprocess the buffer
429 * if it changes, and avoid false positives for performance reasons.
430 * WineD3D doesn't even know the vertex buffer any more, it is managed
431 * by the client libraries and passed to SetStreamSource and ProcessVertices
434 * We have to distinguish between vertex shaders and fixed function to
435 * pick the way we access the strided vertex information.
437 * This code sets up a per-byte array with the size of the detected
438 * stride of the arrays in the buffer. For each byte we have a field
439 * that marks the conversion needed on this byte. For example, the
440 * following declaration with fixed function vertex processing:
448 * { POSITIONT }{ NORMAL }{ DIFFUSE }{SPECULAR }
449 * [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]
451 * Where in this example map P means 4 component position conversion, 0
452 * means no conversion, F means FLOAT16_2 conversion and C means D3DCOLOR
453 * conversion (red / blue swizzle).
455 * If we're doing conversion and the stride changes we have to reconvert
456 * the whole buffer. Note that we do not mind if the semantic changes,
457 * we only care for the conversion type. So if the NORMAL is replaced
