vf_overlay video filter accepts expressions in its parameters. In
'frame-by-frame' evaluation mode it recalculates them regularly, but
incoming video frame size changes did not reflect in their values. So if
width or height of any source videos in expressions as parameters,
they stayed on their initial values. This patch corrects this bug.
Please consider to put this patch into the official ffmpeg source tree.
