This is silly.  Just call gst_pad_try_set_caps() with the new size.
If the new caps negotiation succeeds, good, you will now be getting
a stream with the new size.  (If it fails, I think you need to recall
gst_pad_try_set_caps() with the old size.)

Back in the 0.6 days, I had this working with videotestsrc ! xvideosink.
However, I never checked it in, since we were in a freeze, and
subsequently lost the patch.
