300 * The vertex buffer FVF doesn't help with finding them, we have to use the decoded vertex declaration and pick the things
301 * that concern the current buffer. A problem with this is that this can change between draws, so we have to validate
302 * the information and reprocess the buffer if it changes, and avoid false positives for performance reasons.
304 * We have do destinguish between vertex shaders and fixed function to pick the way we access the
305 * strided vertex information.
307 * This code sets up a per-byte array with the size of the detected stride of the arrays in the
308 * buffer. For each byte we have a field that marks the conversion needed on this byte. For example,
309 * the following declaration with fixed function vertex processing:
317 * { POSITIONT }{ NORMAL }{ DIFFUSE }{SPECULAR }
318 * [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]
320 * Where in this example map P means 4 component position conversion, 0 means no conversion, F means FLOAT16_2 conversion
321 * and C means D3DCOLOR conversion(red / blue swizzle).
323 * If we're doing conversion and the stride changes we have to reconvert the whole buffer. Note that we do not mind if the
324 * semantic changes, we only care for the conversion type. So if the NORMAL is replaced with a TEXCOORD, nothing has to be
325 * done, or if the DIFFUSE is replaced with a D3DCOLOR BLENDWEIGHT we can happily dismiss the change. Some conversion types
326 * depend on the semantic as well, for example a FLOAT4 texcoord needs no conversion while a FLOAT4 positiont needs one
