TODO:
remove global/static vars
reduce the time wasted on the mem transfer
implement everything in C at least (done at the moment but ...)
unroll stuff if instructions depend too much on the prior one
we use 8x8 blocks for the horizontal filters, opendivx seems to use 8x4?
move YScale thing to the end instead of fixing QP
write a faster and higher quality deblocking filter :)
make the mainloop more flexible (variable number of blocks at once
(the if/else stuff per block is slowing things down)
compare the quality & speed of all filters
split this huge file
border remover
optimize c versions
try to unroll inner for(x=0 ... loop to avoid these damn if(x ... checks
smart blur
commandline option for the deblock / dering thresholds
put fastmemcpy back
dont use #ifdef ARCH_X86 for the asm stuff ... cross compilers? (note cpudetect uses ARCH_X86)
...
