66407b9877 glcontext: fix get_current_gl_api on x11/nvidia drivers
They require to get_proc_address some functions through the
platform specific {glX,egl}GetProcAddress rather than the default
GL library symbol lookup.

eba6f6b80f gl/calayer: provide the exact GL api version for the wrapped context
Otherwise we could end up being mistaken for the diference between a
gl3 and a gl2 context resulting in a failure getting the list of
extensions from the wrapped context due to the difference between
glGetString and glGetStringi for the GL_EXTENSIONS token.

0ad168a258 gl/cocoa: reduce custom main loop latency
This fix a very slow rendering rate regression that only
happens when using gst-launch, i.e. in the case where
the main thread does not run any NSApp loop.

Git bisect reported it has been introduced by the commit
e10d2417e2:
"move to CGL and CAOpenGLLayer for rendering".

Then the commit 7d46357627:
"gstglwindow_cocoa: fix slow render rate" attempted to fix
the slow rendering rate problem when using gst-launch.

At least for me it does not work. I tried several
combinations, for example to flush CA transactions in the
custom app loop, as mentioned in the doc, but the only solution
that fixes the slow rendering is by reducing the loop latency.
From what I tested, no need to put less than 60ms, even if the
framerate has an interval much lower (16.6ms for 60 fps).

0c459222f8 gstglwindow_cocoa: fix slow render rate
In gst_gl_window_cocoa_draw we used to just call setNeedsDisplay:YES. That was
creating an implicit CA transaction which was getting committed at the next
runloop iteration. Since we don't know how often the main runloop is running,
and when we run it implicitly (from gst_gl_window_cocoa_nsapp_iteration) we only
do so every 200ms, use an explicit CA transaction instead and commit it
immediately. CA transactions nest and debounce automatically so this will never
result in extra work.

019367c128 glwindow: remove width/height from _draw()
Depending on the platform, it was only ever implemented to 1) set a
default surface size, 2) resize based on the video frame or 3) nothing.
Instead, provide a set_preferred_size () that elements/applications
can use to request a certain size which may be ignored for
videooverlay/other cases.

50a11e4a77 gl/cocoa: Disable hack for NSApp iteration with a special #define
The hack causes deadlocks and other interesting problems and it really
can only be fixed properly inside GLib. We will include a patch for
GLib in our builds for now that handles this, and hopefully at some
point GLib will also merge a proper solution.

A proper solution would first require to refactor the polling in
GMainContext to only provide a single fd, e.g. via epoll/kqueue
or a thread like the one added by our patch. Then this single
fd could be retrieved from the GMainContext and directly integrated
into a NSRunLoop.

4a736caded gl/cocoa: fix uncaught exception 'unrecognized selector sent to instance'
Need to set the ':' as the reshape method now takes one parameter.
For the story, the GstGLNSView was previously inheriting from
NSOpenGLView which has a reshape function without any parameter.
Now the GstGLNSView inherits from NSView and we re-use the reshape
function manually.

02a0b92d9d gl/cocoa: Fix for building on Mac OS X 10.10
Using NSApp directly seems to confuse something, as the compiler
was expecting an id<NSFileManagerDelegate>. Switched to using
[NSApplication sharedApplication], and specified the delegate
protocol on the window class as well.

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.
