ea711807d8 glcolrconvert: fix YUY2 download 
- The shader was outputing the wrong values compared with raw
  videotestsrc.
- deal with the texture edge properly.
- properly sample the 2x1 rectangle for the u and v values
- don't double sample the y value

435810b238 gl/cocoa: Always update our viewport if Cocoa tells us something has changed 
The visible rect and bounds might be the same as before, but Cocoa
might've changed our viewport without us nothing. This happens if
you hide the view and show it again.

b1a5ae7c0d gl/cocoa: Update viewport according to the current clipping 
We have to update the GL viewport if the NSView is only partially
visible. Otherwise the content of the frame will be visibly offset.

9ff86a3c54 gl/cocoa: Improve the NSApplication initialization 
This is only for non-Cocoa apps but previously caused a 2 second
waiting during startup for Cocoa apps. This is unacceptable.

Instead we now check a bit more extensive if something actually
runs on the GLib default main context, and if not don't even
bother waiting for something to happen from there.

02b3e26854 gl/cocoa: Switch to a plain NSView subclass instead of NSOpenGLView 
We don't and can't use NSOpenGLView as it's supposed to be used and
it gets into our way by being to clever in various situations.

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.
