058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * if it changes, and avoid false positives for performance reasons.
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * WineD3D doesn't even know the vertex buffer any more, it is managed
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * by the client libraries and passed to SetStreamSource and ProcessVertices
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * as needed.
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * We have to distinguish between vertex shaders and fixed function to
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * pick the way we access the strided vertex information.
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * This code sets up a per-byte array with the size of the detected
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * stride of the arrays in the buffer. For each byte we have a field
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * that marks the conversion needed on this byte. For example, the
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * following declaration with fixed function vertex processing:
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * POSITIONT, FLOAT4
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * NORMAL, FLOAT3
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * DIFFUSE, FLOAT16_4
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * SPECULAR, D3DCOLOR
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * Will result in
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * { POSITIONT }{ NORMAL }{ DIFFUSE }{SPECULAR }
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * [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]
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * Where in this example map P means 4 component position conversion, 0
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * means no conversion, F means FLOAT16_2 conversion and C means D3DCOLOR
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * conversion (red / blue swizzle).
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * If we're doing conversion and the stride changes we have to reconvert
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * the whole buffer. Note that we do not mind if the semantic changes,
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * we only care for the conversion type. So if the NORMAL is replaced
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * with a TEXCOORD, nothing has to be done, or if the DIFFUSE is replaced
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * with a D3DCOLOR BLENDWEIGHT we can happily dismiss the change. Some
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * conversion types depend on the semantic as well, for example a FLOAT4
058c0c53c37f5cb271aeb3c385c10766f84f4aefvboxsync * texcoord needs no conversion while a FLOAT4 positiont needs one
