I would move this after 10/19 and possibily considering squashing the
two. The overall diff of the 2 patches combined is pretty understandable.

As I read this 'output' used to be the current format on the sink pad
and we use the height from there.

Now we use 'patrition->uds_source.height' which I read being
initialized in uds_partition() to:

	partition->uds_source = *window;

With 'window' being the parameter passed to uds_partition().

Is this correct ?

Same question as per the uds module
