e9864e2e3e glwindow: remove unused draw_unlocked function
The functionality is provided by draw anyway and is leftover from
X11's specific threading requirements that no longer apply.

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.

8c56e1bba7 gl: Try harder to load symbols from the correct place
This commit makes the loading of the GModules threadsafe, and
always first tries to load the symbol for the GL library that
is selected for the current context. Only then it falls back
to looking into the current module (NULL), and only as a last
resort the context specific function (e.g. eglGetProcAddress())
is called.

Also add configure parameters to select the names of the library
modules instead of using the defaults, and let the defaults be
independent of the G_MODULE_SUFFIX.

in a while something was rendered.

6300c2ef1b [901/906] glx: use the display handle from the global display
Intel drivers require the display handles be the same for context
sharing to occur.  Also solves some cases of use after free of the
display when integrating with gstreamer-vaapi.

See https://bugs.freedesktop.org/show_bug.cgi?id=41736 for the intel bug.

303b77eeff [890/906] x11: add display subclass
GstGLDisplayX11 holds the display connection and name.  Each thread requires
it's own X11 Display connection (initialised from name) due to the fact that
we do not want to call XInitThreads().  Doing so would result in segfaults
when integrating with GUI toolkits Gtk, Qt, etc.

The Display connection is for OpenGL platforms where a constant display is
required in order to share contexts (egl).  In the case of a wrapped context
(added later), we do not have GstGLWindow to retreive the display from so a
'master' connection is used instead.
