| 39 | verify that everything workes as it should | |
| 40 | reduce the time wasted on the mem transfer | |
| 41 | implement dering | |
| 42 | implement everything in C at least | |
| 43 | figure range of QP out (assuming <256 for now) | |
| 44 | unroll stuff if instructions depend too much on the prior one | |
| 45 | we use 8x8 blocks for the horizontal filters, opendivx seems to use 8x4? | |
| 46 | move YScale thing to the end instead of fixing QP | |
