/*
Known Issues:
* The motion estimation is somewhat at the mercy of the input, if the input
frames are created purely based on spatial interpolation then for example
a thin black line or another random and not interpolateable pattern
will cause problems
Note: completly ignoring the "unavailable" lines during motion estimation
didnt look any better, so the most obvious solution would be to improve
tfields or penalize problematic motion vectors ...
* If non iterative ME is used then snow currently ignores the OBMC window
and as a result sometimes creates artifacts
* only past frames are used, we should ideally use future frames too, something
like filtering the whole movie in forward and then backward direction seems
like a interresting idea but the current filter framework is FAR from
supporting such things
* combining the motion compensated image with the input image also isnt
as trivial as it seems, simple blindly taking even lines from one and
odd ones from the other doesnt work at all as ME/MC sometimes simple
has nothing in the previous frames which matches the current, the current
algo has been found by trial and error and almost certainly can be
improved ...
