Windows that set empty input shapes get n_rects of 0 when querying them
later, which makes sense, but the code that interpreted the result
translated it into a NULL input shape, which meant it was the same as
the bounding region. As such, an empty input shape would actually get
interpreted as a full input shape!
We, ourselves, set an empty input shape on tray icon windows in
gnome-shell since we would handle the picking ourselves. This meant that
we'd actually get the MetaSurfaceActorX11 when hovering over the tray
icon, instead of the ShellGTKEmbed that we capture events on and react
to.
This fixes weird tray icon behavior in gnome-shell.
We clip the input region to the client rect, so the client rect should
be up to date before we fetch the input region.
This fixes popup windows not working in GTK+2 under Wayland.
We should also update the shape / input regions when the window is
reconfigured for a complete fix, so that making an O-R window bigger
doesn't confuse mutter, but let's leave that to a future commit.
The coordinates in ConfigureNotify *should* be the coordinates of the
client window; using the coordinates of the frame window compensated for
a problem with the interpretation of StaticGravity for some clients but
broke other clients.
This reverts commit f4f70afe31.

The merge of the commit af46ef3b 'meta_window_new: clean up error handling'
to the wayland branch accidentally added an extra call to meta_error_trap_push(),
meaning that we leaked one level of error traps for each new window.
Fixes warning:
Gdk-WARNING **: XSetErrorHandler() called with a GDK error trap pushed.

Before, we were using the root window coordinates of the client window,
rather than the toplevel frame window. This caused various Java programs
and programs like VirtualBox and WINE to get confused about where their
window actually is, and make bad ConfigureRequests when trying to
position their windows in the future.
Remove the mass of code here by just using window->rect.
The existing workspace management code is quite hairy, with plenty of
logic inline in all of window.c, workspace.c, and screen.c, making it
hard to understand or make changes to, since you might forget to change
several of the other places the code was around.
Rewrite the internal workspace management logic so that it's
centralized and all in window.c. Document the invariants we need to
maintain, and ensure that these invariants are properly kept, with
asserts in various places.
Extensive testing on gnome-shell did not bring up any issues, and this
is a considerable cleanup.
Since commit 467465c99c we use meta_stage even on x11 which sets
clutter_stage_set_user_resizable to FALSE.
This messes things up because we ought to ignore the properties on the window
but we apperently didn't.
There is no reason why we'd want to manage the stage window.

GTK+ likes to set these, well, _NET_WM_OPAQUE_REGION in particular, to
the same value. Save some expensive and processing when this happens. We
should probably make GTK+ smarter.
When workspaces-only-on-primary is set and a window is moved back to the
primary, we also move it to the active workspace to avoid the confusion
of a visible window suddenly disappearing when crossing the monitor border.
However when the window is not actually moved by the user, preserving the
workspace makes more sense - we already do this in some cases (e.g. when
moving between primary monitors), but miss others (unplugging the previous
monitor); just add an explicit user_op parameter as used elsewhere to cover
all exceptions.

Rather than calculate it speculatively with the current properties
which may be too new or too out of date, make sure it always fits
with the proper definition. We update it when we update the toplevel
window for X11, and when a Wayland surface is committed with a newly
attached buffer.
There's a race here. If an OR window hides itself, moves, and then shows
itself, we will send a ConfigureNotify for the old size of the window
and might receive it after the client moves itself, causing us to show
the window at the wrong location.
Simply not sending the ConfigureNotify is the easiest thing to do.
Before we unmanage, we send a ConfigureNotify to clients to let them
know if their frame is destroyed. We do this for OR windows too, even if
we really probably shouldn't.
This is based off of the client_rect. Since we listen to ConfigureNotify
on OR windows, we'll receive the event. If we don't ever update the
client_rect when moving or resizing OR windows, then we'll send
ourselves a ConfigureNotify for a 0x0 size and then think that the
client chose a new size for itself. Since our get_paint_volume is based
on that rectangle, but the TFP code inside Cogl uses XGetGeometry
itself, we get weird flickering artifacts.
For Wayland, we want to have everything possible in terms of the frame
rect, or "window geometry" as the Wayland protocol calls it, in order
to properly eliminate some flashing when changing states to fullscreen
or similar.
For this, we need to heavily refactor how the code is structured, and
make it so that meta_window_move_resize_internal is specified in terms
of the frame rect coordinate space, and transforming all entry points
to meta_window_move_resize_internal.
This is a big commit that's hard to tear apart. I tried to split it
as best I can, but there's still just a large amount of changes that
need to happen at once.
Expect some regressions from this. Sorry for any temporary regression
that this might cause.
The last commit added support for the "appmenu" button in decorations,
but didn't actually implement it. Add a new MetaWindowMenuType parameter
to the show_window_menu () functions and use it to ask the compositor
to display the app menu when the new button is activated.

The requested_rect is a strange name for it, because it's not actually
the rect that the user or client requested all the time: in the case of
a simple move or a simple resize, we calculate some of the fields
ourselves.
To the MetaWindow subclass implementations, it just means "the rect
before we constrained it", so just use the name unconstrained_rect.
This also makes it match the name of the MetaWindow field.
It looks weird to have Alt+Space pop up under the cursor instead
of the top-left corner of the window, and the Wayland request will
pass through the coordinates as well.
Add it to the compositor interface, and extend the
_GTK_SHOW_WINDOW_MENU ClientMessage to support it as well.
We already do it in the theme code, but not the actual WM code. Since
we include the left/right borders, it only seems fair to include the
bottom border.
This effectively makes it so that shading a window means that the
client window "slot" has 0 height.
Realistically, the user rect contains the unconstrained window
rectangle coordinates that we want to be displaying, in case
something in the constraints change.
Rename it to the "unconstrained_rect", and change the code to always
save it, regardless of current state.
When metacity was originally being built, the purpose of the user
rect was a lot less clear. The code only saved it on user actions,
with various other calls to save_user_window_placement() and a force
mechanism sprinkled in to avoid windows being snapped back to odd
places when constraints changed.
This could lead to odd bugs. For instance, if the user uses some
extension which automatically tiles windows and didn't pass
user_action=TRUE, and then the struts changed, the window would be
placed back at the last place a user moved it to, rather than where
the window was tiled to.
The META_IS_USER_ACTION flag is still used in the constraints code
to determine whether we should allow shoving windows offscreen, so
we can't remove it completely, but we should think about splitting
out the constrainment policies it commands for a bit more
fine-grained control.

It's been long enough. We can mandate support for these, at least
at build-time. The code doesn't actually compile without either
of these, so just consider that unsupported.
We previously separated out MetaDisplay and MetaScreen. mutter
would only manage one screen, but we still kept a list of screens
for simplicity.
With Wayland support, we no longer care about the ability to
manage more than one screen at a time. Remove this by killing
the list of screens, in favor of having just one MetaScreen
in MetaDisplay.
We also kill off active_screen at the same time, since it's
not necessary anymore.
A future cleanup should merge MetaDisplay and MetaScreen. To avoid
breaking API, we should probably keep MetaScreen around as a dummy
type.
At one point, it was supported to run mutter without a compositor,
but we don't allow that any longer. A lot of code already assumes
display->compositor exists and doesn't check for a NULL pointer,
so just kill the rest of the checks.
This is specifically about managing X11 windows, not necessarily
running as an X11 compositor. By that I mean that this code is
still used for XWayland windows, and event handling is still and
modesetting / monitor management is still in core/.
This is also a fairly conservative move. We don't move anything
like screen.c or bell.c in here, even though those are really
only for X11 clients.
