Commit 4f2bb583bf changed things so that the compositor used
clutter_threads_add_repaint_func_full (CLUTTER_REPAINT_FLAGS_POST_PAINT
to get after-paint notification and send _NET_WM_FRAME_DRAWN, but this
doesn't actually work, since Clutter will already have blocked for
VBlank before calling post-paint functions.
The result is that frame synced toolkits like GTK 3.8 will normally
only be able to draw every other frame.
Since ::paint doesn't work either, a new function
clutter_stage_set_paint_callback() has been added to Clutter
(and will be included in the 1.14 branch)

We have no need for normally reported events during grabs. In fact, it
might be harmful. A plugin might grab the keyboard through
meta_begin_modal_for_plugin() and then expect events to be reported to
the grab window they provide. If meanwhile this XIGrabDevice is
issued, events might start being reported normally to one other of our
windows breaking the plugin event processing.
In particular, on an empty workspace, we set input focus to our
no_focus_window. Then, if gnome-shell calls
meta_begin_modal_for_plugin() and meta_display_freeze_keyboard(), in
that order, input events will start being reported to no_focus_window.
There are two issues with this. One is that no_focus_window isn't
selecting for XI input events and thus the server discards them
completely. But even if that is fixed, events being reported to any
window other than the one gnome-shell expects - the clutter stage
window - means that events will stop reaching it.

This will make it possible to implement input source switching in
gnome-shell using the popular modifiers-only keybinding that's
implemented on the X server through an XKB option.

We'll use this in gnome-shell to freeze the keyboard right before
switching input source and unfreeze it after that's finished so that
we don't lose any key events to the wrong input source.

If a binding is updated with a clear set of strokes (effectively
disabling it) we aren't signaling that the binding changed and thus
the previous strokes will continue to be grabbed.
This fixes that and tries to do a better effort at checking if the
binding changed or not.

gnome-shell has traditionally just called XSetInputFocus when wanting to
set the input focus to the stage window, but this might cause strange,
hard-to-reproduce bugs because of an interference with mutter's focus
prediction. Add API to allow gnome-shell to focus the stage window that
also updates mutter's internal focus prediction state.

If an app pops up an OR window and sets input focus to it, like
Steam does, we'll think the focus window is null, causing us to
think the app is not focused.
OR windows should not be special if they get input focus, where
the input focus would be set to NULL. Instead, the window should
be marked as focused.

Mutter previously defined display->focus_window as the window that the
server says is focused, but kept display->expected_focus_window to
indicate the window that we have requested to be focused. But it turns
out that "expected_focus_window" was almost always what we wanted.
Make MetaDisplay do a better job of tracking focus-related requests
and events, and change display->focus_window to be our best guess of
the "currently" focused window (ie, the window that will be focused at
the time when the server processes the next request we send it).

The hierarchy handling is handled in the shell by adding stuff
directly to the uiGroup, and we have a dedicated actor for
the overview there, so we don't need this anymore.

Make it a static function for now, but this will be a private
function soon, replacing meta_window_lost_focus. This should
contain no functional changes, only cosmetic indentation changes,
so best viewed with ignorews=1 or -w or -b, you know the drill.

Clients using _NET_WM_MOVERESIZE to start a drag operation may encounter
a race condition if the user presses and releases a mouse button very
fast, getting "stuck" in a grab state. While this is easily fixed with
the user pressing the button or hitting Escape as the EWMH spec suggests,
its's still a bit of annoyance for users.
After starting a grab operation, check that the button is actually pressed
by the client, and if not, cancel the grab operation. This prevents the
stuck grab in a race-free way, although it requires an extra round-trip
to the server.
With client-side decorations becoming more popular, the use of
_NET_WM_MOVERESIZE is on the rise, thus this bug is seen more frequently
than before.

As we only had one string-array preference so far, we didn't bother
with adding a generic way to handle string-array preferences, and
just handled the preference in question explicitly. However we are
going to parse another string-array setting, so generalize the
existing code to make it reusable for that case.

g-ir-scanner will emit more warnings regarding broken GTK-Doc

This essentially just moves install_corners() from the compositor, through
the core, into the UI layer where it arguably should have been anyway,
leaving behind stub functions which call through the various layers. This
removes the compositor's special knowledge of how rounded corners work,
replacing it with "ask the UI for an alpha mask".
The computation of border widths and heights changes a bit, because the
width and height used in install_corners() are the
meta_window_get_outer_rect() (which includes the visible borders but not
the invisible ones), whereas the more readily-available rectangle is the
MetaFrame.rect (which includes both). Computing the same width and height
as meta_window_get_outer_rect() involves compensating for the invisible
borders, but the UI layer is the authority on those anyway, so it seems
clearer to have it do the calculations from scratch.

XUngrabKey() doesn't work for XI2 grabs and XI2 doesn't provide API
with similar functionality. As such, we have to refactor the code a
bit to be able to call XIUngrabKeycode() for each key binding, then
reload keybindings and finally grab the new ones.
