bc399a0403 glvideomixer: fix blending with low-alpha sources 
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).

e0459f1b65 gl: download whenever we have sysmem capsfeatures 
Otherwise we could pass on a RGBA formatted buffer and downstream would
misinterpret that as some other video format.

Fixes pipelines of the form

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.
