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