c90bc869e5 doc: Workaround gtkdoc issue
With gtkdoc 1.22, the XML generator fails when a itemizedlist is
followed by a refsect2. Workaround the issue by wrapping the
refsect2 into para.

df7370bc2a compositor: fix rectangle obscure test to clamp against the output frame size
Rather than one of the input pad video info's.

The test checking this was not constraining the output frame size

fa6dbaeb6c glmixer: Implement GstVideoAggregator::find_best_format()
Without this, we will fixate weird pixel-aspect-ratios like 1/2147483647. But
in the end, all the negotiation code in videoaggregator needs a big cleanup
and videoaggregator needs to get rid of the software-mixer specific things
everywhere.

dbbfba76ea tests: Add a check for the new compositor pad-is-obscured optimization
We verify that all the buffers on an obscured sinkpad are skipped by overriding
the map() function in the GstVideoMeta of the buffers to set a variable when
called. We also test that the buffers do get mapped when they're not obscured.

Blame^WCredit for the GstVideoMeta map() idea goes to Tim.

070777498f compositor: Only map the frame from a buffer if it will be used
It's a waste of resources to map it if it won't be converted
or used at all. Since we moved the frame mapping down, we need
to use the GST_VIDEO_INFO accessor macros now in the code above
that instead of the GST_VIDEO_FRAME accessor macros.

8f1edb69f4 compositor: Skip pads that are completely obscured by a higher zorder pad
For each frame, compare the frame boundaries, check if the format contains an
alpha channel, check opacity, and skip the frame if it's going to be completely
overwritten by a higher zorder frame. The check is O(n^2), but that doesn't
matter here because the number of sinkpads is small.

More can be done to avoid needless drawing, but this covers the majority of
cases. See TODOs. Ideally, a reverse painter's algorithm should be used for
optimal drawing, but memcpy during compositing is small compared to the CPU used
for frame conversion on each pad.

63c776adee videoaggregator: Remove broken timestamps-going-backwards check
This would've also triggered if for some reason the segment was updated
in such a way that PTS went backwards, but the running time increased. Like
what happens when non-flushing seeks are done.

We're doing a proper buffer-from-the-past check a few lines below based on the
running time, which is the only time we should care about here.

26d3057d98 aggregator: Query latency on first incoming buffer.
And keep on querying upstream until we get a reply.

Also, the _get_latency_unlocked() method required being calld
with a private lock, so removed the _unlocked() variant from the API.
And it now returns GST_CLOCK_TIME_NONE when the element is not live as
we think that 0 upstream latency is possible.
