+The hash function is CRC32 using polynomial 0xEDB88320.
+However, the hashed data is calculated incorrectly in TexMod: it's simply BytesPerPixel * Width * Height, from the beginning of the data (that is mapped using LockRect).
+The problem is that it doesn't take the pitch into account and BytesPerPixel may be wrong for some rare formats (not sure about that).
