Toplevels get the main monitor from their MetaWindow and have no main
monitor when the toplevel is not mapped.
Subsurfaces get the main monitor from their parent surface.
DnD and cursors get the main monitor from the current cursor position no
matter if the cursor is actually being shown or not.

Having an always-on-top window affects focus granting logic if the
to be showing window overlaps with any of them. Instead of triggering
the focus denying logic if a new window ever so slightly touches an
always-on-top window to only triggering if it's covered more than 60% by
always-on-top windows.
This is intended to make using always-on-top windows a bit less annoying
and not cause as many unintended focus-on-map denials.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3879>
When we show a window, we'll check if it overlaps with an existing
always-on-top window with the intention to deny focus. However, we did
this potentially before having placed the window, meaning we effectively
checked as if it was placed at (0, 0), which created unexpected results.
Instead check the overlap state after placing. A window placement test
case is added to verify this works as expected.

Replace a boolean argument and a temporary MetaWindow struct field with
a `MetaPlaceFlag` passed where relevant. This includes
`meta_window_move_resize_internal()` and `meta_window_constrain()`, as
placement may happen during constraining, and also
`meta_window_force_placement()`.
The struct field (denied_focus_and_not_transient) was only ever set in
meta_window_show(), before meta_window_force_placement(), and
immediately unset as a side effect of that. In .._show() we'll always
force placement if the window wasn't already placed, and in
meta_window_constrain(), we'd only ever call meta_window_place() if the
window wasn't already placed, meaning the variable would only ever be
relevant during `meta_window_show()`. Having it as a flag makes that
relationship and temporary state clearer.

The function checking whether a 'always-on-top' window covers the
showing window now has that in the name, to make it more obvious. That
function was also changed to use the more common way of iterating a
list, and now uses auto cleanup pointers for the list.
The condition itself was updated to follow the current coding style.

This avoids the following critical warning happening sometimes when a
Wayland client exits taking all its window with it in an arbitrary
order:
CRITICAL: meta_window_set_stack_position_no_sync: assertion 'window->stack_position >= 0' failed

When a transient window becomes transient, check if the parent is
sticky, and if it is, make the transient sticky as well. This handles
situations where e.g. a utility dialog (such as search and replace) is
opened on a sticky window, also making the utility dialog sharing the
same stickyness state.
This is also more in line with the semantics of making a window sticky,
where transient would implicitly become sticky as a side effect.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3870>
If a transient window is sticky (visible on all workspaces) and it gets
activated, we'd call move_worskpace() which would effectively unstick
it, which is rather unexpected. It'd also effectively unstick its parent
as well, due to moving a transient window also moves its descendants and
ascendants.

Instead use an abstract "logical monitor id" that is generated from the
logical monitor. Instead of using low level numbers from the mode
setting devices, use either data from the EDID, or the connector, if the
EDID is not useful.
This should help with windows remembering monitor positions when the
same monitor reappears but with another mode setting device ID.

That was only there to force updating MetaFrame's bounds
but that is something that is already updated in
MetaWindowX11.move_resize_internal. So just drop all of that

When a client resizes on its own, make sure the new size is passed
through the window constraints machinery directly, to trigger any
potential window management rule that might apply.
Fix a couple of tests to make use of this behavior by introducing a new
'wait_size' command that waits until a window has been resized to a
expected size.
This replaces the fix introduced in 0e736af301 ("window: Ensure
constraints after a Wayland client resize").

Starting the timeout to move from hidden to suspended before the window
is mapped means we don't have a previous window configufration which we
need to get the new window configuration with the suspended state.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3731>
Instead of initializing to 'suspended', which will send the `SUSPENDED`
xdg_toplevel state, set it to hidden at first. If the window is placed
on an inactive workspace, it'll eventually enter the 'suspended' state,
but will have had some time in non-suspended state to get map, even if
not visibly.
This fixes inital suspended state when mapping a window maximized.

This, in contrast to meta_window_should_be_showing() reports whether a
window should be showing despite not being showable. This is useful to
know the intended visibility state that should happen in the immediate
future.

When the monitors change meta_window_update_for_monitors_changed is
called which is responsible for updating window->monitor. It however can
go through the entire window placement and constraint machinery before
it's able to do so. In this period window->monitor points to the old
MetaMonitor where the monitor number doesn't reflect the index into the
MonitorManager anymore.
Avoid relying on the window->monitor->number and go through the Monitor
directly.

When multiple configure requests sent to the wayland client within a sort period, maximized windows may end up in wrong position and cover struts. To avoid this, queue a resize when the resize event sent by the wayland client results a changed size or position to ensure that the final size and position will be always right.

meta_window_handle_ungrabbed_event() triggers the show of the window menu in
gnome-shell via meta_window_show_menu() on hold of Meta + right mouse button
click.
Since meta_display_handle_event() was refactored lately and now forwards a
lot more events to Clutter (including the one triggering the window menu),
gnome-shell now sees this event after the menu has opened, figures that the
source-actor is outside of the menu, and immediately closes the menu again.
This is the correct behavior from the PopupMenuManager on the gnome-shell
side, it is the responsibility of the event handler that opens the menu (aka
meta_window_handle_ungrabbed_event()) to return CLUTTER_EVENT_STOP and stop
event propagation.
So fix this issue by adding a return value to
meta_window_handle_ungrabbed_event() and stopping event propagation in case
the event opened the window menu.
While at it, also return CLUTTER_EVENT_STOP for events triggering window
drags, so we can drop the extra check for that in
meta_display_handle_event().

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

MetaWindow always tries to have a main monitor: If the frame rect is empty
and the window has not been positioned, in meta_window_constructed() we fall
back to asking the backend for the current monitor, and in
meta_window_wayland_update_main_monitor() we fall back to
meta_window_find_monitor_from_id(), which then falls back to the primary
monitor.
In general this means that window->monitor is always set as long as there is
a monitor around.
For getting the highest-scale-monitor the window is on, we currently rely
completely on the frame rect. If the frame rect is empty, we set the
highest-scale-monitor to NULL. Since we usually know though which monitor
the window is, or will be on, and window->monitor is even set to that, we
can just fall back to window->monitor for the highest-scale-monitor.
This makes sure ::highest-scale-monitor-changed is emitted right after the
window is created, and it's set to the correct monitor that the window will
be on. This in turn means that we can send a correct wp_fractional_scale
fraction_scale event to clients right away.
