I applied this patch, modified to return a frame size range on the
sink pad. Also, I believe both frame size and frame interval
enumeration should base their decision making on the crop rectangle
at the sink pad, not on the format at the source pads, due to the
crop/compose re-org patch from Philipp.

The updated patch is attached.
