[MPlayer-dev-eng] vf_dsize rounding error

[Alan Curry]

In -vf dsize, resolution is calculated as a float and then assigned to an int
without any explicit rounding, so unlucky sizes can be computed as X.999999
and rounded down, ending up 1 less than the correct size. It would be better
to round to the nearest int.
