  49. TODO:

  50. reduce the time wasted on the mem transfer

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

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

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

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

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

  56. compare the quality & speed of all filters

  57. split this huge file

  58. optimize c versions

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