341	* GL_ARB_half_float_vertex is not supported.
342	*
343	* Note for d3d8 and d3d9:
344	* The vertex buffer FVF doesn't help with finding them, we have to use
345	* the decoded vertex declaration and pick the things that concern the
346	* current buffer. A problem with this is that this can change between
347	* draws, so we have to validate the information and reprocess the buffer
348	* if it changes, and avoid false positives for performance reasons.
349	* WineD3D doesn't even know the vertex buffer any more, it is managed
350	* by the client libraries and passed to SetStreamSource and ProcessVertices
351	* as needed.
352	*
353	* We have to distinguish between vertex shaders and fixed function to
354	* pick the way we access the strided vertex information.
355	*
356	* This code sets up a per-byte array with the size of the detected
357	* stride of the arrays in the buffer. For each byte we have a field
358	* that marks the conversion needed on this byte. For example, the
359	* following declaration with fixed function vertex processing:
360	*
361	* POSITIONT, FLOAT4
362	* NORMAL, FLOAT3
363	* DIFFUSE, FLOAT16_4
364	* SPECULAR, D3DCOLOR
365	*

371	* means no conversion, F means FLOAT16_2 conversion and C means D3DCOLOR
372	* conversion (red / blue swizzle).
373	*
374	* If we're doing conversion and the stride changes we have to reconvert
375	* the whole buffer. Note that we do not mind if the semantic changes,
376	* we only care for the conversion type. So if the NORMAL is replaced
377	* with a TEXCOORD, nothing has to be done, or if the DIFFUSE is replaced
378	* with a D3DCOLOR BLENDWEIGHT we can happily dismiss the change. Some
