* opengl. This means D3DCOLOR attributes with fixed function vertex
* processing, FLOAT4 POSITIONT with fixed function, and FLOAT16 if
* GL_ARB_half_float_vertex is not supported.
*
* Note for d3d8 and d3d9:
* The vertex buffer FVF doesn't help with finding them, we have to use
* the decoded vertex declaration and pick the things that concern the
* current buffer. A problem with this is that this can change between
* draws, so we have to validate the information and reprocess the buffer
* if it changes, and avoid false positives for performance reasons.
* WineD3D doesn't even know the vertex buffer any more, it is managed
* by the client libraries and passed to SetStreamSource and ProcessVertices
* as needed.
*
* We have to distinguish between vertex shaders and fixed function to
* pick the way we access the strided vertex information.
*
* This code sets up a per-byte array with the size of the detected
* stride of the arrays in the buffer. For each byte we have a field
* that marks the conversion needed on this byte. For example, the
* following declaration with fixed function vertex processing:
*
* POSITIONT, FLOAT4
* NORMAL, FLOAT3
* DIFFUSE, FLOAT16_4
* SPECULAR, D3DCOLOR
*
* Will result in
* { POSITIONT }{ NORMAL }{ DIFFUSE }{SPECULAR }
* [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]
*
* Where in this example map P means 4 component position conversion, 0
* means no conversion, F means FLOAT16_2 conversion and C means D3DCOLOR
* conversion (red / blue swizzle).
*
* If we're doing conversion and the stride changes we have to reconvert
* the whole buffer. Note that we do not mind if the semantic changes,
* we only care for the conversion type. So if the NORMAL is replaced
* with a TEXCOORD, nothing has to be done, or if the DIFFUSE is replaced
* with a D3DCOLOR BLENDWEIGHT we can happily dismiss the change. Some
* conversion types depend on the semantic as well, for example a FLOAT4
* texcoord needs no conversion while a FLOAT4 positiont needs one
