When prepare_gl fails in the right way (or the wrong way?), we
end up creating the leader window twice, and as a side effect,
creating two instances of the "Virtual core pointer" device, which
is bad news for grabs.

After commit 447bc18c48 EGL on X11 broke.
But the handling of the GL context also was quite awkward because it was
unclear who was responsible for ensuring it got reset.
Change that by making gdk_gl_context_clear_current_if_surface() return
the context (with a reference because it might be the last reference) it
had unset, so that after changing EGL properties the code that caused
the clearing can re-make it current.
This moves the responsibility to the actual code that is dealing with
updating properties and frees the outer layers of code from that task.
And that means the X11 EGL code doesn't need to care and the code in the
Wayland backend that did care can be removed.

Make begin_frame() set a rendering colorstate and depth, and provide it
to the renderers via gdk_draw_context_get_depth() and
gdk_draw_context_get_color_state().
This allows the draw contexts to define their own values, so that ie the
Cairo and GL renderer can choose different settings for rendering (in
particular, GL can choose GL_SRGB and do the srgb conversion; while
Cairo relies on the renderer).
Make our visual selection code prefer fbconfigs that are
'srgb framebuffer capable', and mark the surface as 'is srgb'
in this case.
This arranges things so that GSK knows not to use an offscreen
for converting contents back to srgb in the end.
We still only differentiate between high bit depth or not, but we now
choose at the end instead of the start, which makes it easier to adapt
to a different method of choosing.
'XPointerUngrabInfo' appears unused since
commit 26cbf87d7d ("New approach for grab tracking code")
Remove it.

In fetch_net_wm_check_window(), before updating the wmspec_check_window, a
check is performed to verify a 15s difference between last_wmspec_check_time
and the current monotonic time.
The comment suggests that this check is done to ensure that it doesn't check
for a new check window repeatedly over and over again. While that was the case
origionally, currently the last_wmspec_check_time only gets updated when
wmspec_check_window is set, which is already checked earlier, making the time
check useless.
This check causes issues on cold boots where gtk4 applications are not able
to obtain the wmspec_check_window until 15 seconds after boot, making gtk
unable to check for extended wm_hints during that time.

If there somehow end up being no `supported_versions`, `ctx` would end
up being dereferenced before being initialised. While I think that’s
unlikely, the compiler doesn’t know that, so let’s just initialise the
variable unconditionally.

This drops cursor and eraser source names to account for their removal
from GdkInputSource so that GDK_DEBUG=input debug message correctly
prints source type in X11 environment.

This fixes monitor enter and leave events on X11, and probably other
things. Previously, it looks like the coordinates were relative to the
top left corner of the window shadow and so never changed.
Whether or not switches include shapes to indicate their ON/OFF
state is currently controlled by the stylesheet (in particular
the HighContrast style).
However there are use cases for both using the HighContrast style
without shapes, and for using shapes with the regular stylesheet,
so follow the newly added "show-status-shapes" setting instead.

It started out as busywork, but it does many separate things. If I could
start over, I'd take them apart into multiple commits:
1. Remove G_ENABLE_DEBUG around GDK_DEBUG_*() calls
This is not needed at all, the calls themselves take care of it.
2. Remove G_ENABLE_DEBUG around profiling code
This now enables profiling support in release builds.
3. Stop poking _gdk_debug_flags and use GDK_DEBUG_CHECK()
This was old code that was never updated.
4. Make !G_ENABLE_DEBUG turn off GDK_DEBUG_CHECK()
The code used to
#define GDK_DEBUG_CHECK(...) false
#define GDK_DEBUG(...)
which would compile away all the code inside those macros. This
means a lot of variable definitions and debug utility functions
would suddenly no longer be used and cause compiler errors.
This is implemented using a new xdg_toplevel `suspended` state, and is
meant for allowing applications to know when they can stop doing
unnecessary work and thus save power.
In the other backends, the `suspended` state is set at the same time as
`minimized` as it's the closest there is to traditional windowing
systems.
Sometimes, GLX can decide to use the previous request serial when faking
XErrors via __glXSendError() (look through the Mesa sources to enjoy).
This can cause the error trap we just installed to not feel responsible
for the error. And that makes GDK decide to immediately abort the
application.
That is not what we or GLX want.
So we use a no-op X Request to bump the request number so that when GLX
does its shenanigans, it uses a serial that our error trap will catch.
Fixes a crash in mutter's CI which apparently manages to drive GLX
without an X server.
In error cases, glXCreateContextAttribsARB() will always return NULL so
it is enough to run the loop until the first non-NULL context is
returned.
And at that point, we can just look at the return value and ignore all
errors.
Instead of trapping errors for the whole loop trying to create GL
contexts, trap them once per GL context.
Apparently GLX does throw an error when a too high version is requested
and doesn't just return NULL and then that error lingers when we try
lower versions.
Fixes#5857
We may try to update the XRR outputs and Crtcs when they're changing in
the server, and so we may get BadRROutput that we're currently not
handling properly.
As per this, use traps and check whether we got errors, and if we did
let's ignore the current output.
It's not required to call init_randr13() again because if we got errors
it's very likely that there's a change coming that will be notified at
next iteration during which we'll repeat the init actions.
The display xevent signal connection takes the ownership of the stream
until we get a valid event, so it should manage the stream lifetime.
So make this clearer, by automatically removing the stream reference
when we disconnect from the xevent signal handler.
We create a new stream during gdk_x11_selection_input_stream_new_async()
then such stream is referenced when passed to the task via
g_task_return_pointer(), so there's no need to reference it again before
returning it, or we'd end up leaking.

XWayland (at least on gnome-shell) does not support SGI_swap_control,
which we were using to unset the swap interval.
It does support EXT_swap_control though, which is the more modern
version of the same thing, so this commit adds support for that.
And now GDK_DEBUG=no-vsync gives me >1000fps instead of just 60fps,
