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 |
