TODO:
reduce the time wasted on the mem transfer
unroll stuff if instructions depend too much on the prior one
move YScale thing to the end instead of fixing QP
write a faster and higher quality deblocking filter :)
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
optimize c versions
