e559c30a20 allow changing of the spatial_decomposition_count and quantization tables
per frame (this is untested as the encoder does not use it yet)

fa731ccd4e scaling obmc tables under #if 0 also by 4 (yes they where forgotten apparently)

7d7f57d939 store halfpel filter coefficients in the header as well as the
flag for diagonal interpolation

the primary reason for this change is that previously MC up to 1/4 pel
matched H.264 exactly and that increases the risk of stumbling over
patents

secondly this allows 0.10 db or more quality gain by choosing a longer
filter and the filter could also be chosen optimally for each frame
though that of course would cause speed loss at the decoder and encoder
side ...

a68ca08e30 cleanup mc_block()
perform interpolation steps in such an order that halfpel interpolation
could be done per picture
this also makes mc_block() match h.264 for the 1/4 pel cases so that the
use of the h264 functions for some cases does not introduce a fantastic mess

ce611a27be Change rounding of the horizontal DWT to match the vertical one.
This allows some simplifications and optimizations and should
not have any effect on quality.
