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 ...

perform interpolation steps in such an order that halfpel interpolation

this also makes mc_block() match h.264 for the 1/4 pel cases so that the
