0b2e5c3f95 glmixer: override the caps query in order to 'convert' capsfeatures 
Otherwise, it is only possible for the sink pads and the src pads to
have the exact same caps features.  We can convert from any feature
to another feature so support that.

6491af9ffc 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.

94efcd2595 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.

7b1a853888 GstGLWindow, GstGLImagesink, x11: Scale navigation events on resized windows 
If window is resized, GstStructure pointer values have to be rescaled to
original geometry. A get_surface_dimensions GLWindow class method is added for
this purpose and used in the navigation send_event function.
