6a37bf9bb9 gl: Don't restore the viewport on function exit
Doing so involves retrieving the current viewport from OpenGL which as
with any glGet operation, is expensive.

This means that the various sinks need to reset the viewport on draw.

In the process, fix resizing on cocoa.

c5b5ef16d3 gl: GST_EXPORT -> GST_GL_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

de16dc2555 gl: Fix backwards compat GST_GL_TYPE_* functions/macros
These have to be macros instead of inline function as they must behave
more or less like an integer literal, i.e. include the function call.

f532e699df gl/window: remove use of main_context_push/pop_thread_default()
No-one's using/depending on it (it would have criticalled and not worked)
and it's causing more problems than it's solving.  Store the GMainContext
in the public struct instead for subclasses to optionally use instead of
relying on the push/pop state to be correct.

1403a6871f glwindow: Hide navigation specific internal API and add API to asynchronously send navigation events
Exposing the navigation thread's main context, GSourceFuncs and structs called
key_event and mouse_event is exposing a bit too much of the internals. Let's
just go with two functions to asynchronously send navigation events on the
window with the same API as the synchronous ones.

63bbe9406a glwindow: add API to request a resize event on the next draw
- glimagesink needs to be able to resize the viewport on aspect ratio
  changes resulting from either caps changes or 3d output mode changes.
- Performing a glViewport outside the GstGLWindow::resize callback
  will not have the winsys' stack of viewports required to correctly
  place the output frame.

Provide a function to request a resize on the next draw event from the
winsys.

Also track size changes inside the base GstGLWindow class rather
than in each subclass.

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.

f803a9e746 GstGLWindow: Introduce navigation thread
This thread dispatches navigation events. It is needed to avoid deadlocks
between window backend threads that emit navigation events (e.g. X11/GMainLoop
thread) and consumers of navigation events such as glimagesink, see
https://bugzilla.gnome.org/show_bug.cgi?id=733661

GstGlWindow_x11 thread is changed to invoke the navigation thread for navigation
dispatching, instead of emiting the event itself. Othe backends beside X11 do
not dispatch navigation events yet, but should use this thread when dispatching
these events in the future.

The navigation thread is currently part of GstGLWindow and not implemented in
separate subclasses / backends. This will be needed in the future.

gst_gl_window_x11_get_surface_dimensions is also changed to use a cached value
of the window's width, height. These values are now retrieved in the X11
thread, function gst_gl_window_x11_handle_event. This change is needed because
otherwise the XGetWindowAttributes gets called from the navigation thread,
leading to xlib aborting due to multithreaded access (if XInitThreads is not
called before, as is the case for gst-launch)

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.

4f117323b8 [705/906] x11: don't shutdown in _finalize
The window's loop could be still running when _finalize is called
and if we destroy the display connection it will never be closed.

Add _open and _close vfuncs to GstGLWindow so that subclasses can
start up and shutdown at the right time.
