60 TODO:

61 reduce the time wasted on the mem transfer

62 unroll stuff if instructions depend too much on the prior one

63 move YScale thing to the end instead of fixing QP

64 write a faster and higher quality deblocking filter :)

65 make the mainloop more flexible (variable number of blocks at once

66 (the if/else stuff per block is slowing things down)

67 compare the quality & speed of all filters

68 split this huge file

69 optimize c versions

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