"warning: 'match_tile_mode' may be used uninitialized in this function", it
complains. It thinks it's not unused because of other values of
window->tile_mode, but other complex logic ensures that it can't be
META_TILE_MAXIMIZED, so this is a safe commit.
Windows that have minimum widths larger than the screen can't be maximized,
even though we put them in a maximized state and allow users to do so:
the window just won't change size and position. Fix this by simply not giving
the option to maximize, like what happens for non-resizable windows.

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.

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.

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.

For maximized windows, titlebars cannot be used to reposition or
scale the window, so if an application does not use it to convey
useful information (other than the application name), the screen
space occupied by titlebars could be put to better use.
To account for this use case, a setting for requesting that windows'
titlebars should be hidden during maximization has been added to
GTK+, add support for this in the window manager.
https://bugzilla.gnome.org/show_bug.cgi?id=665617
The current code requires windows to be resizable to be considered
for tiling, which excludes all maximized/tiled windows. While this
restriction concurs with the desired behavior for edge-tiling, it
feels overly restrictive for keybindings.
As the edge-tiling code in update_move() already ensures the above
restriction, it seems save to remove it from the can_tile_maximized()
function, assuming that windows that are not meant to be tiled or
maximized won't provide a maximize function.

Usually tiling involves a size change and the frame is redrawn
automatically, however this is not the case when switching directly
between left- and right-tiled.
Ensure that a redraw happens in that case as well.

Move preferences to GSettings, using mainly shared schemas from
gsettings-desktop-schemas.
Unlike GConf, GSettings support is not optional, as Gio is already
a hard dependency of GTK+.

meta_window_move_resize_frame operates much like
meta_window_move_resize, but ensures the window
and its frame (if present) will fit within the
specified dimensions.

If we are moving in snap mode (shift pressed) we don't want to tile. We must
also cancel any pending tiling if snap mode is activated during the move drag.

meta_window_get_current_tile_area() computes the area where the tiled window
should be based on the current pointer position but that's only meaningful
when the user is actually dragging the window.
When running the tiling constrain the pointer might be on other monitor and at
that point the window jumps to this other monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=642580
Since the frame window size that meta_window_move_resize() uses depends
on whether the window has horizontal/vertical resize functionality, we
need to update this flag before we resize the window.
https://bugzilla.gnome.org/show_bug.cgi?id=659854
If a window had a type hint intended for override-redirect windows
like NOTIFICATION, we ended up with a window that was decorated but
with a frame type of FRAME_TYPE_LAST, causing assertion failures.
Fix this by making recalc_window_features() just call
meta_window_get_frame_type().
https://bugzilla.gnome.org/show_bug.cgi?id=599988
_NET_FRAME_EXTENTS should contain the difference between where a window asked
to be placed, and where it is. Ideally, this should be the same as the visible
extents.
https://bugzilla.gnome.org/show_bug.cgi?id=659848
A window can specify geometry that it is placed at. We need to exclude invisible
borders when calculating where to place the window, otherwise the window will have
a strange offset.

If XRANDR is availible, we track the first (or primary) output per
crtc (== xinerama monitor) so when the monitors change we can try
to find the same output and move windows there. If we can't find the
original monitor in the new set (or XRANDR is not supported) we move
the window to the primary monitor.

Different bits of code were using slightly different checks to test
whether a window was an attached dialog. Add a new
meta_window_is_attached_dialog(), and use that everywhere.
Also, freeze the is-attached status when the window is first shown,
rather than recomputing it each time the caller asks, since this could
cause problems if a window changes its type after it has already been
attached, etc. However, if an attached window's parent is destroyed,
or an attached window changes its transient-for, then fix things up by
destroying the old MetaWindow and creating a new one (causing
compositor unmap and map events to be fired off, allowing the display
of the window to be fixed up).
Remove some code in display.c that tried to fix existing windows if
the gconf setting changed, but which didn't actually do anything (at
least under gnome-shell). However, if 654643 was fixed then the new
behavior with this patch would be that changing the gconf setting
would affect new dialogs, but not existing ones.
https://bugzilla.gnome.org/show_bug.cgi?id=646761
get_outer_rect now returns the visible region, and a new get_input_rect
method returns the boundaries of the full frame, including the possible
invisible regions. When undecorated, both do the samething.

There were actually *two* MetaFrameGeometry structs: one in theme-private.h,
one in frame.h. The latter public struct was populated by a mix of (void*)
casting and int pointers, usually pulling directly from the data in the private
struct.
Remove the public struct, replace it with MetaFrameBorders and scrap all
the pointer hacks to populate it, instead relying on both structs being used
in common code.
This commit should be relatively straightforward, and it should not do any
tricky logic at all, just a sophisticated find and replace.

In preparation for switching to handling the output shape purely by what we
paint, stop applying a shape to the frame of the window. Even when we restore
handling the output shape, this will change the behavior with respect to input;
transparent areas between the frame and the contents will stop clicks rather
than passing them through, but that is arguably at least as expected
considering how that we decorate shaped windows with a frame all around.
https://bugzilla.gnome.org/show_bug.cgi?id=644930
When detaching/attaching a dialog, we were only updating
appears-focused on the parent if the child itself was focused, but in
fact, we need to do it if the child has an attached child which is
focused too.
To simplify the case of detaching a focused subtree from its parent,
we change meta_window_propagate_focus_appearance() to use
@window->display->focus_window as the window to add/remove as the
attached_focus_window, and @window only as the starting point to
propagate from. That way we can propagate focus-removal up to
@window's (soon-to-be-ex-)ancestors without having to remove it from
its descendants as well.

Don't set a window's xtransient_for if it would create a loop. Since
this is the only place we ever set xtransient_for, we can therefore
assume everywhere else that it does not loop.

Since version 3.0, GTK+ has support for style variants. At the moment,
themes may provide a dark variant, which can be requested by
applications via GtkSettings. The requested variant is exported to
X11 via the _GTK_THEME_VARIANT property - support this property, in
order to pick up the correct style variant in the future.

If a window is not maximizable, then that probably means it looks dumb
at very large sizes. Even if its hints would allow you to manually
resize it to a large size, don't allow automatically tiling it to half
the screen.

An ARGB window with a frame is likely something like a transparent
terminal. It looks awful (and breaks transparency) to draw a big
opaque black shadow under the window, so clip out the region under
the terminal from the shadow we draw.
Add meta_window_get_frame_bounds() to get a cairo region for the
outer bounds of the frame of a window, and modify the frame handling
code to notice changes to the frame shape and discard a cached
region. meta_frames_apply_shapes() is refactored so we can extract
meta_frames_get_frame_bounds() from it.
https://bugzilla.gnome.org/show_bug.cgi?id=635268
If a window can not be tiled, e.g. due to its minimum size hints,
dragging away from the top after activating the maximize tile preview
does not cancel the maximization request, the only way to do so is by
hitting Escape.
To fix, reset the tiling state in the maximize-tile code path as
well if necessary.

Apparently the "fox" toolkit doesn't set WM_CLIENT_MACHINE; while we
