Test toy app
When basetransform gets a pad alloc with a caps it doesn't support it simply
rejects with not-negotiated. When dynamically switching pipeline elements,
upstream might issue a pad_alloc to a basetransform element that was just added
and linked in place of another element. This pad_alloc will probably have the
same caps that was being used with the previous element and might not be
supported by the newly added basetransform.
I propose that basetransform instead of failing, suggested upstream a caps that
they could agree and keep the pipeline flowing.
I'll attach a test case in python.
