Hello,

Some time ago I made a commit [1] to fix a reverse-negotiating problem in
basetransform. But this was reverted by wim [2] because it shows some
flickering in test-scale.

But I believe this behaviour in the test-scale is correct as it is always
trying to reverse-negotiate the caps, and now it just wrongly negotiate it.
(can be seen from the logs)

The current implementation is wrong because now the original requested caps are
compared with the transformation of the suggested caps to decide to use proxy
in the basetransform element. But as we will return a buffer of the suggested
caps this comparison does not make sense anymore and the basetransform can do a
proxy where it should not.
