Oh ok, so i guess just something to pack the bits. I guess something more
efficient will come later on... :)

Thanks

Binary runlength encoding in bitplanes, the current code uses parallel
runlength encoders. Runlengths are written out by a modified Golomb
coder. Should be free of IP issues but not very efficient because we
don't take any advantage of spatial correlation, there is no context
sensitive entropy coding.
