  54. TODO:

  55. reduce the time wasted on the mem transfer

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

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

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

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

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

  61. compare the quality & speed of all filters

  62. split this huge file

  63. optimize c versions

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