  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
