  49. TODO:

  50. reduce the time wasted on the mem transfer

  51. implement everything in C at least (done at the moment but ...)

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

  53. we use 8x8 blocks for the horizontal filters, opendivx seems to use 8x4?

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

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

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

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

  58. compare the quality & speed of all filters

  59. split this huge file

  60. border remover

  61. optimize c versions

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

  63. smart blur

  64. commandline option for   the deblock / dering thresholds

  65. put fastmemcpy back

  66. dont use #ifdef ARCH_X86 for the asm stuff ... cross compilers? (note cpudetect uses ARCH_X86)

  67. ...
