  58. TODO:

  59. reduce the time wasted on the mem transfer

  60. unroll stuff if instructions depend too much on the prior one

  61. move YScale thing to the end instead of fixing QP

  62. write a faster and higher quality deblocking filter :)

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

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

  65. compare the quality & speed of all filters

  66. split this huge file

  67. optimize c versions

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