When we move focus elsewhere when unmanaging a window, we *need* to move
the focus, so if the target is globally active, move the focus to the
no-focus-window in anticipation that the focus will normally get moved
to the right window when the target window responds to WM_TAKE_FOCUS.
If the window doesn't respond to WM_TAKE_FOCUS, then focus will be left
on the no-focus-window, but there's no way to distinguish whether the
app will respond or not.

When a client spontaneously focuses their window, perhaps in response
to WM_TAKE_FOCUS we'll get a FocusOut/FocusIn pair with same serial.
Updating display->focus_serial in response to FocusOut then was causing
us to ignore FocusIn and think that the focus was not on any window.
We need to distinguish this spontaneous case from the case where we
set the focus ourselves - when we set the focus ourselves, we're careful
to combine the SetFocus with a property change so that we know definitively
what focus events we have already accounted for.

Initial placement during meta_window_constrain() can result in changes
to the borders, so we need to recompute our border sizes after
constraining. This fixes incorrect window borders on
initially maximized windows.

Currently the only way to move a window to another monitor via
keyboard is to start a move operation and move it manually using
arrow keys. We do have all the bits of a dedicated keybinding in
place already, so offer it as a more comfortable alternative.

Some drivers which support RandR 1.4 may not support setting
or getting the primary output, therefore mutter should trap
and ignore any relevant errors.
The modesetting driver exposes this problem when used in
combination with the nvidia binary driver using RandR 1.4
offloading.
Also use a local display variable instead of calling
meta_get_display () every time.
Do this by duplicating the current code and porting it to use
X again. A better approach would involve our own event structures,
and I really don't want to do that right now. We can clean this up
later.
The grab_window might be NULL, in which case we have a full-screen
grab, but we might still in a grab. Correct the check by asking
whether we're in a grab op or not.
When unmaximizing, we changed bits of window state, then called out
to code that used the frame extents *before* we cleared old cached
extents. Clear the cache up-front as soon as we change the window
state.

When _GTK_FRAME_EXTENTS changes, we need to redo constraints on
the window - this matters in particular if the toolkit removes
invisible borders when a window is maximized, since otherwise
the maximized window will be positioned as if it still has
invisible borders.

We require a MetaWindow to properly implement some of the requests
for xdg_surface, so add a way to have an unmapped MetaWindow that
we can store properties on, that we later map when the client
attaches a buffer...
The compiler is not quite smart enough to figure out that the condition
for setting the "compositor" variable matches a later condition for
accessing it, so express this in a way the compiler will understand.
For clarity, rename meta_window_get_outer_rect() to match terminology
we use elsewhere. The old function is left as a deprecated
compatibility wrapper.
Instead of passing around MetaFrameBorders, compute it when we need it.
This also allows us to know that we are using MetaFrameBorders only for windows
with frames (where it is meaningful) and not for frameless windows, which
can have custom borders which we need to interpret differently.
https://bugzilla.gnome.org/show_bug.cgi?id=707194
Cache the computed border size so we can fetch the border size at
any time without worrying that we'll be spending too much time in
the theme code (in some cases we might allocate a PangoFontDescription
or do other significant work.)
The main effort here is clearing the cache when various bits of window
state change that could potentially affect the computed borders.
https://bugzilla.gnome.org/show_bug.cgi?id=707194
There are extensive places in the code where we convert between the client
rectangle and the frame rectangle. Instead of manually doing it use
new helper functions on MetaWindow and the existing meta_window_get_outer_rect().
This fixes a number of bugs where the computation was being done incorrectly,
most of these bugs are with the recently added custom frame extents, but
some relate to invisible borders or even simply to confusion between the
window and frame rectangle.
Switch the placement code to place the frame rectangle rather
than the client window - this simplifies things considerably.
https://bugzilla.gnome.org/show_bug.cgi?id=707194
What we want to achieve is that the dialog is visually centered
on the parent, including the decorations for both, and making sure
that CSD/frame_extents are respected.

Use the "hotplug_mode_update" connector property indicating that the
screen settings should be updated: get a new preferred mode on hotplug
events to handle dynamic guest resizing (where you resize the host
window and the guest resizes with it).

Clients like on-screen keyboards try not to take focus when the user clicks
on their window by setting the Input hint to false. However, due to GTK+ and
GDK bugs, the public API for setting the Input hint to false don't remove
WM_TAKE_FOCUS from WM_PROTOCOLS, unintentionally putting them into Globally
Active mode.
These clients also expect that since they don't want to take focus, they want
the focus to remain on the existing window. In this case, for clients like
on-screen keyboards, it's so they can send synthesized keyboard events to the
focused window.

Since this is stored in an array full of data that will be copied
around, we can't rely on pointer addresses for every item in a stack
not changing.
I don't see any reason that we even have a weak pointer, either.
This code looks safe to me without it.
