  49. TODO:

  50. remove global/static vars

  51. reduce the time wasted on the mem transfer

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

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

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

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

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

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

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

  59. compare the quality & speed of all filters

  60. split this huge file

  61. border remover

  62. optimize c versions

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

  64. smart blur

  65. commandline option for   the deblock / dering thresholds

  66. put fastmemcpy back

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

  68. ...
