Rather than using a magic lookup table with no explanations, let's add liberal comments to the code to explain what this tiling scheme is and how to encode/decode it efficiently. It's not so mysterious after all -- just reordering bits with some XORs thrown in. v2: Correct copyright identifier. Fix spelling error. Switch space_4 to a LUT. Fix comment typo. Use LUT instead of space_x tricks. Fallback on generic rather than split up unaligned writes. v3: Correct stride order (fixes crash loading). Correct coordinate system mishap.
