/* Certain declaration types need some fixups before we can pass them to opengl. This means D3DCOLOR attributes with fixed
* function vertex processing, FLOAT4 POSITIONT with fixed function, and FLOAT16 if GL_NV_half_float is not supported.
*
* 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.
*
* 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 }

*
* 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
