To flag filters that can work with variable frame size changes
all the time in graph. So no rescalers are need to be inserted or
filtergraph reset.

Once all such filters are flaged with such capability then code will be
added so auto inserted rescale filter is inserted where neccesarry to
filters in
filtergraph that do not support dynamic width/height changes.
