435	*
436	* Note for d3d8 and d3d9:
437	* The vertex buffer FVF doesn't help with finding them, we have to use
438	* the decoded vertex declaration and pick the things that concern the
439	* current buffer. A problem with this is that this can change between
440	* draws, so we have to validate the information and reprocess the buffer
441	* if it changes, and avoid false positives for performance reasons.
442	* WineD3D doesn't even know the vertex buffer any more, it is managed
443	* by the client libraries and passed to SetStreamSource and ProcessVertices
444	* as needed.
445	*
446	* We have to distinguish between vertex shaders and fixed function to
447	* pick the way we access the strided vertex information.
448	*
449	* This code sets up a per-byte array with the size of the detected
450	* stride of the arrays in the buffer. For each byte we have a field
451	* that marks the conversion needed on this byte. For example, the
452	* following declaration with fixed function vertex processing:
453	*
454	* POSITIONT, FLOAT4
455	* NORMAL, FLOAT3
456	* DIFFUSE, FLOAT16_4
457	* SPECULAR, D3DCOLOR
458	*
459	* Will result in
460	* { POSITIONT }{ NORMAL }{ DIFFUSE }{SPECULAR }
461	* [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]

463	* Where in this example map P means 4 component position conversion, 0
464	* means no conversion, F means FLOAT16_2 conversion and C means D3DCOLOR
465	* conversion (red / blue swizzle).
466	*
467	* If we're doing conversion and the stride changes we have to reconvert
468	* the whole buffer. Note that we do not mind if the semantic changes,
469	* we only care for the conversion type. So if the NORMAL is replaced
470	* with a TEXCOORD, nothing has to be done, or if the DIFFUSE is replaced
471	* with a D3DCOLOR BLENDWEIGHT we can happily dismiss the change. Some
