I may be late to the party here, but mark my words, if the cache is changed
to anything other than plain, complete files in a standard file format, it
will be the final nail in the coffin for my already tenuous faith in Linden
Lab's collective engineering sense.

Also note, if we're going to do the uncompressed cache thing, XORing the
file will eliminate the possibility of zero-copy DMAing of the texture
directly from disk into VRAM. XOR is still more overhead than having the
texture not hit the processor at all.
