A lot of code did something similar to:
MetaFrameBorders borders;
if (window->frame)
meta_frame_calc_borders (window->frame, &borders);
else
meta_frame_borders_clear (&borders);
Sometimes, the else part was omitted and we were unknowingly using
uninitalized values for OR windows. Clean this up by just testing
for a NULL frame in meta_frame_calc_borders and clearing for the
caller if so.

Since we're going to be evaluating the work area at startup now, we need
to make sure that we don't iterate over workspaces before they're assigned.
The easiest way to do this is to make sure that meta_window_get_workspaces
doesn't crash.

Returns the matching tiled window. This is the topmost tiled window in a
complementary tile mode that is:
- on the same monitor;
- on the same workspace;
- spanning the remaining monitor width;
- there is no 3rd window stacked between both tiled windows that's
partially visible in the common edge.

After the changes in style handling in GTK+, mutter's tooltips no
longer match the tooltip style used in applications. Given that
all buttons in the default layout are well-known, killing tooltips
altogether rather than fixing the styling issues looks like a valid
approach.

Windows that start up in a size that is almost as big as the workarea create
extra work for the user (resizing or maximizing) so save the user's time by
detecting such windows and automaximize them.
https://bugzilla.gnome.org/show_bug.cgi?id=671677
Basically we don't really want to create windows that are almost maximized in
size but not actually maximized. This creates work for the user and makes it
very difficult to use and resize manually.
So set the newly unmaximized window size to the previously used size or 80% of the
size of the current workarea (attempting to retain natural aspect ratio if
possible), whichever is smaller.

Some modifiers like NumLock and ScrollLock don't make sense in
keybindings, which is why we ignore them when matching keybindings
to events. We should do the same in Javascript, so add an accessor
function.
https://bugzilla.gnome.org/show_bug.cgi?id=665215
The move-to-corner keybindings weren't treated as user actions, which
resulted in them not affecting the saved position - they weren't
always being treated as sticky. Marking them as a user action revealed
bugs in the positioning logic that were hidden by the constraint
code applied to automated moves. Fix those as well. Bug tracked
down by Mariusz Libera.

We currently sync the number of workspaces with the corresponding
preference. This is not really useful with GNOME Shell's dynamic
handling of workspaces, not least as the setting is effectively
ignored. Worse, it will trigger writes to dconf on login, slowing
down startup, so add a setting to indicate that workspaces are managed
dynamically and really ignore the num-workspaces setting when set.

We were relying on GTK+ emitting GtkWidget::style-updated during
widget initialization to create the GtkStyleContexts used for
window decorations. A recent GTK+ update broke this assumption,
so do the necessary initialization ourselves.

Mutter originally started out with the idea that only a subset of the total
API was exposed to plugins, so some APIs are duplicated on MutterPlugin.
We've long since abandoned that idea; remove these wrappers.

After _unmanage the object is semantically dead even if technically it's not,
so remove the prefs listener here to prevent it being called for a dead
object.
In particular this fixes a crash when starting up gnome-shell with at least
one gimp utility window opened which causes mutter to create a MetaWindow for
it only to immediately get an UnmapNotify afterwards which causes mutter to
unmanage the MetaWindow. Afterwards prefs_changed_callback is called for this
dead MetaWindow and tries to dereference the window->monitor pointer which is
already NULL.
