framepositioner: Stop lying about the source size
Basically we were advertising that the source size would be the size of the track if it hadn't been defined by end user, but since we started to let scaling happen in the compositor, this is not true as the source size is now the natural size of the underlying video stream. Remove the unit test and reimplemented using a validate scenario which make the test much simpler to read :=)
