+TODO:
+verify that everything workes as it should
+reduce the time wasted on the mem transfer
+implement dering
+implement everything in C at least
+figure range of QP out (assuming <256 for now)
+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
