These were leftovers from times when GL(ES) 1.x was still supported.
As we require HAVE_COGL_GL and/or HAVE_COGL_GLES2 to be defined, all
cases for checking both are now redundant.

My motivation was at first to replace cairo_rectangle_t with graphene_rect_t
but noticed nothing uses it anywhere: Shell/Kiosk/Gala; so it is safe
to just drop and people could still use the new_to_framebuffer ctor
and handle setting up things themselves if needed.

The helper doesn't do anything that makes it worth
to be exposed as public API. End-users, such as GNOME Shell could have
an in-tree helper if they end up using it that much.

The shell might raise and make windows recent for another workspace when
an app gets activated on another workspace. Making the windows only
recent on the current workspace thus results in inconsistent focus when
another window of the same app is closed.

There are existing extensions that implement desktop icons as
a combination of a GTK program and a small extension to make
the wayland window behave as if it was of type DESKTOP on X11.
That's quite painful, as it requires reimplementing WM behavior
that is already implemented in mutter itself (stacking, stickiness,
skip-taskbar, ...), as well as modifying gnome-shell to consider
the window in addition to "real" DESKTOP windows (workspace-switch
animations, ctrl-alt-tab, ...).
In addition to that, other extensions may also have special handling
of DESKTOP windows, and their code cannot easily be monkey-patched
to handle "alternative" desktop icons.
This whole game of whack-a-mole can easily be avoided by allowing
desktop-icons extensions to mark their desktop windows as DESKTOP,
so do just that.

Assigning the corresponding stack layer of DESKTOP windows is
currently X11 specific, because there is no way for wayland
clients to set the DESKTOP window type.
This is about to change, so move the code to the generic layer
handling.

Change the order of events to adhere to the Wayland specification for
wl_keyboard.enter, which mandates:
> The compositor must send the wl_keyboard.modifiers event after
> this event.
Mutter currently sends the modifiers event before the enter event,
which may break applications that require information about the focused
surface in order to properly handle the modifiers.

These functions ends-up calling gdk-pixbuf for loading textures/bitmaps
from a file and they don't seem to be used anywhere.

Create a fake monitor region right of the right-most monitor and if a
horizontal barrier extends into that region, fail the barrier. Barriers
are aligned on the top/left edge of the pixel so the most natural
barrier of (e.g. 0-1024) is also wrong - it's one pixel into the next
monitor.
Check this for nonexisting screens on the right too to avoid clients
suddenly failing when multiple monitors are present.

Assuming two 1920x1080 screens next to each other: a horizontal barrier
starting at 1920 going east is always outside the left screen.
Assuming two 1920x1080 screens on top of each other: a vertical barrier
starting at 1080 going south is always outside the top screen.

When running headless, only the invalid modifiers are advertised.
That breaks with the NVIDIA proprietary driver which then rejects the
buffers created with the invalid modifier, and that kills Xwayland,
meaning that running Xwayland on top of a mutter based compositor
headless is not possible.
The reason the modifiers are not sent is because AddFb2 is not supported
when running headless.
Other compositors (weston, wlroots) would still send the modifiers even
without AddFb2, and Xwayland works fine on those compositors when
running headless.
Remove the requirement for AddFb2 to send the modifiers, so that
Xwayland can work fine on top of mutter headless with the NVIDIA
proprietary driver.

`clutter_actor_destroy()` queues a stage update. Under certain
circumstances - i.e. when run in a very slow container - this can race
with the stage update triggered by the following
`clutter_virtual_input_device_notify_button()`, occasionally resulting in
`wait_stage_updated()` to return before the
`on_event_return_propagate()` callbacks ran, making the test fail.
This notably became more common since
8f27ebf87e (clutter/frame-clock: Start next update ASAP after idle period)
landed.
Thus wait for a stage update to happen after `clutter_actor_destroy()`,
preventing the race.

For frame updates in response to sporadic user interaction, this results
in input → output latency somewhere between the minimum possible and the
minimum plus the length of one display refresh cycle (assuming the frame
update can complete within a refresh cycle).
Applying a max_render_time based deadline which corresponds to higher
than the minimum possible latency would result in higher effective
minimum latency for sporadic user interaction.
This was discovered by Ivan Molodetskikh, based on measurements
described in https://mastodon.online/@YaLTeR/110848066454900941 .

Instead of g_get_monotonic_time. This makes sure last_presentation_time_us
advances by refresh_interval_us.
Doesn't affect test results at this point, but it will with the next
commit.

When more than one refresh interval has passed since
last_presentation_time_us.
I honestly can't tell if the previous calculation was correct or not,
but I'm confident the new one is, and it's simpler.

Every `mtk_x11_error_trap_push()` must be paired
with an `mtk_x11_error_trap_pop[_with_return]()` call
otherwise all future errors will be caught and ignored
even if they shouldn't be.
