406	* GL_ARB_half_float_vertex is not supported.
407	*
408	* Note for d3d8 and d3d9:
409	* The vertex buffer FVF doesn't help with finding them, we have to use
410	* the decoded vertex declaration and pick the things that concern the
411	* current buffer. A problem with this is that this can change between
412	* draws, so we have to validate the information and reprocess the buffer
413	* if it changes, and avoid false positives for performance reasons.
414	* WineD3D doesn't even know the vertex buffer any more, it is managed
415	* by the client libraries and passed to SetStreamSource and ProcessVertices
416	* as needed.
417	*
418	* We have to distinguish between vertex shaders and fixed function to
419	* pick the way we access the strided vertex information.
420	*
421	* This code sets up a per-byte array with the size of the detected
422	* stride of the arrays in the buffer. For each byte we have a field
423	* that marks the conversion needed on this byte. For example, the
424	* following declaration with fixed function vertex processing:
425	*
426	* POSITIONT, FLOAT4
427	* NORMAL, FLOAT3
428	* DIFFUSE, FLOAT16_4
429	* SPECULAR, D3DCOLOR
430	*
431	* Will result in
432	* { POSITIONT }{ NORMAL }{ DIFFUSE }{SPECULAR }
433	* [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]
434	*
435	* Where in this example map P means 4 component position conversion, 0
436	* means no conversion, F means FLOAT16_2 conversion and C means D3DCOLOR
437	* conversion (red / blue swizzle).
438	*
439	* If we're doing conversion and the stride changes we have to reconvert
440	* the whole buffer. Note that we do not mind if the semantic changes,
441	* we only care for the conversion type. So if the NORMAL is replaced
442	* with a TEXCOORD, nothing has to be done, or if the DIFFUSE is replaced
443	* with a D3DCOLOR BLENDWEIGHT we can happily dismiss the change. Some
444	* conversion types depend on the semantic as well, for example a FLOAT4
445	* texcoord needs no conversion while a FLOAT4 positiont needs one
