Bela Bodecs cc83177db4 vf_overlay: handles expression evaluation of frame size change in frame-by-frame evalutaion mode

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
you used width or height of any source videos in expressions as
parameters, they stayed on their initial values. This patch corrects
this bug.
