I didn't find any info on this from the NetSurf documentation, only that
it has separate controls on how much of the image data is buffered as
compressed and how much as uncompressed.

I'm not suggesting that m0n0 would need to do this himself, but it's
something that can be asked from upstream.  Same for 8-bit PNG.
(Storing of uncompressed 8-bit images as 8-bit in memory if they don't 
already do it.)

Inddeed, forking is always a bad idea.  That's why one should work with
upstream.  :-)
