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
|

try to unroll inner for(x=0 ... loop to avoid these damn if(x ... checks
