eb06907fb4 gl/wayland: provide a dummy global_remove function
Even if we don't care about any global objects being removed, wayland
will still error if globals are removed without a corresponding listener
set up for them.  e.g. wl_output hotplugging

ccebcaa586 gl/dispmanx: assign render_rect to window before window_resize
If the `render_rect` for a dispmanx display is set after calling
`window_resize` the resize defaults to the dp_width and dp_height to
determine the location of the render rectangle instead of the correct
dimensions that should be set on the window_egl.

57029ba098 gl/dispmanx: fix deadlock triggered by set_render_rectangle
When the gstglimagesink is started with the option `glimagesink
render-rectangle="<0,0,1920,1080>"`, the pipeline reaches a deadlock.
The reason the deadlock occurs is that the
`gst_gl_window_set_render_rectangle` takes locks on the window, in
addition it calls `window_class->set_render_rectangle(...)` which
executes the `_on_resize` function. Since the `_on_resize` function also
takes locks on the window the deadlock is achieved.

By scheduling the adjustment of the render rectangle through an async
message for `gst_gl_window_dispmanx_set_render_rectangle`, the actual
resize happens in another context and therefore doesn't suffers from the
lock taken in `gst_gl_window_set_render_rectangle`.

This solution follows the same approach as gl/wayland. The problem was
introduced by b887db1. For the full discussion check #849.

These parameters are incorrectly regarded as mutable in G-IR making them

526cb2baa8 gl/eagl: Fix automatic resize behaviour
https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/merge_requests/681
added a layoutSubViews, which never gets called, because it should have been
called layoutSubviews (non-capital "v"). However after fixing that, it still
doesn't work correctly, because window_width/height values are immediately
updated and then draw_cb will never trigger the resize path, because the
values are already up to date.
Update the values inside the resize path again instead, so the check for
entering the resize path is logically always correct.
This makes the layoutSubviews unnecessary, as it only updated the internal
size values prematurely, so it is deleted instead of method naming fixed.

These changes were originally done to avoid accessing UIKit objects on the
main thread, but no additional accesses are added here, only internal
private variable assignments under the same draw_lock, so there should be
no threading issues reintroduced.

8ffea3afb5 gl/eagl: Fix resize condition check in draw_cb to not get called unnecessarily
A CGSize contains CGFloat values (a typedef to double or float), which means
that the values aren't equal, despite it being equal after they are cast to
int by assigning them to window_height/width private members. This leads to
excessive gst_gl_window_resize calls on each frame, at least if the CGFloat
value has a .5 decimal value, e.g. 103.5.
Fix it by storing them as CGFloat instead of gint.

c9d15fec7e glslstage: delete shader on finalize of stage
GLSLstage creates the glShader using glCreateShader, but never calls
glDeleteShader if the glShader is not used anymore. This forces the GL
library to keep the compiled shader around, because it might be used in
the future. Therefore, the glShader is leaked whenever a GLSLStage is
destroyed.

Fix the leak by deleting the glShader when finishing the GLSLStage.

0ea3279df1 gst-libs: gl: Fix documentation typo and clarify gl_memory_texsubimage
`gst_gl_memory_read_pixels` reads pixels from `GLMemory` into the
pointer, effectively writing to it. This is opposite from
`gst_gl_memory_texsubimage` which reads texture data from `read_pointer`
into `GLMemory`.

Both cases are clarified by changing `read_pointer` to `write_pointer`,
and explaining what `gst_gl_memory_texsubimage` does in addition to
referring back to `gst_gl_memory_read_pixels`.

c2b9be5c94 glwindow/winrt: Increase timeout value to 15 seconds
5 seconds might not be enough value for timeout in case an application
is running on a device with very limited computing power.
Note that ANGLE uses 10 seconds timeout value. So even if a timeout
happens here, it's also ANGLE's timeout condition as well
(meaning that bad things will happen either way)

e762f1b376 Revert "gstgldisplay: Add public foreign_display property"
This introduced a possible regression where the EGL display connection
could be leaked when a foreign native display (x11, wayland, etc) could
create a non-foreign EGL display that would never be destroyed.

The underlying problem needed to be solved in a different way.  See
https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/640
for more details.

579db691ed glwindow/winrt: Add warning message if window is being closed from a UI thread
All UI elements will follow Single-Threaded Apartments (STA) model.
As a result, we should access them from dedicated UI thread.
Due to the nature of the threading model, ANGLE will wait the UI
thread while closing internal window/swapchain objects.

A problem here is that when destroying GstGLWindow from the UI thread,
it will wait GstGLContext's internal thread. Meanwhile, the GstGLContext's
internal thread will be blocked because ANGLE wants to access the UI thread.
That will cause a deadlock or exceptions.

In short, application should not try to call
gst_element_set_state(pipeline, GST_STATE_NULL) from a UI thread.
That's a limitation of current implementation.

b4bdb75a80 gstglwindow_x11: fix resize
This patch was taken from #629#note_178766, the comment made
at the time was:

The root issue is a mismatch between the initialization of render_rect
in GstGLWindowX11Private and what's expected in the draw_cb function.
Because render_rect is not explicitly initialized to a width and height
of -1 (unlike gstglwindow_wayland_egl.c which does initialize to -1),
the less-than check for explicitly-set render_rect at gstglwindow_x11.c:453-454
always fails, even when the parent_win has been set and the render rectangle
has never been set.

Maybe this came from copying the similar check in the wayland code? Regardless,
I think the correct inequality should be '<= 0' (on both lines).

Alternatively initialization could be changed, but other sinks, e.g.
xvimagesink don't appear to use -1 to mean "unset" render_rect this way.

The issue can be reproduced by running the example in
tests/examples/gl/qt/videooverlay/ on X11, and resizing the output
window

c506adc950 gl/eagl: don't access UIkit objects on the main thread
This means we cannot access [view layer] or view.bounds from the OpenGL
thread.  This also means that we need to call the main thread when
setting the window handle.  However, we cannot perform that
synchronously as that may deadlock with the application performing the
set_window_handle() call.

We need to defer the actual update and run it asynchronously and wait
for the window handle update internally at each point it is needed.
