1e84482f36 videoaggregator: remove the use of the queued buffer on sink pads
That data is now held by the aggregator class

138e63fd52 videoaggregator: Do not wrongly set the aggregator.segment
The aggregator.segment is not to be initialized by the subclasses but
by the aggregator itself. Moreover, initializing it on start would make
us loose the information coming from the initial seek.

d2f4d20d85 videoaggregator: Do not to release VIDEO_AGGREGATOR_LOCK while setting format info
We should be able to always keep the VIDEO_AGGREGATOR_LOCK while
negotiating caps, this patch introduce that change.

That also implies that we do not need the SETCAPS_LOCK anymore because
now VIDEO_AGGREGATOR_LOCK guarantees that setcaps is not called from
several threads and the gst_aggregator_set_caps method is now
protected.

f4451b764f videoaggregator: Revert the last commit and handle resolutions differences properly
This is about converting the format, not about converting any widths and
heights. Subclasses are expected to handler different resolutions themselves,
like the videomixers already do properly.

We also need to apply the blend paramaters to the alpha channel otherwise
the output of the blend will appear black at low alpha values (< 0.2).

03c21f78b6 glupload: provide the output buffer that is rendered into
Allows callers to properly reference count the buffers used for
rendering.

Fixes a redraw race in glimagesink where the previous buffer
(the one used for redraw operations) is freed as soon as the next
buffer is uploaded.

1. glimagesink uploads in _prepare() to texture n
1.1 glupload holds buffer n
2. glimagesink _render()s texture n
3. glimagesink uploads texture n+1
3.1 glupload free previous buffer which deletes texture n
3.2 glupload holds buffer n+1
4. glwindow resize/expose
5. glimagesink redraws with texture n

The race is that the buffer n (the one used for redrawing) is freed as soon as
the buffer n+1 arrives.  There could be any amount of time and number of
redraws between this event and when buffer n+1 is actually rendered and thus
replaces buffer n as the redraw source.

7a0155e735 glmixer: unref the GstGLUpload in the pad if freed while running
Dynamic pipelines that get and release the sink pads will finalize
the pad without going through gst_gl_mixer_stop() which is where the
upload object is usually freed.  Don't leak objects in such case.

4b1bf9b52a videoaggregator: push the caps event as soon as we receive it
Along with the required mandatory dependent events.

Some elements need to perform an allocation query inside
::negotiated_caps().  Without the caps event being sent prior,
downstream elements will be unable to answer and will return
an error.
