TODO:
verify that everything workes as it should (how?)
reduce the time wasted on the mem transfer
implement dering
implement everything in C at least (done at the moment but ...)
unroll stuff if instructions depend too much on the prior one
we use 8x8 blocks for the horizontal filters, opendivx seems to use 8x4?
move YScale thing to the end instead of fixing QP
write a faster and higher quality deblocking filter :)
do something about the speed of the horizontal filters
make the mainloop more flexible (variable number of blocks at once
	(the if/else stuff per block is slowing things down)
compare the quality & speed of all filters
split this huge file
fix warnings (unused vars, ...)
noise reduction filters
...
