The WALLPAPER style of background painting currently
draws starting in the upper left corner of each monitor.
This isn't really correct, it means the seam between
monitors doesn't match up and edges look unbalanced if
the tile isn't a multipe of monitor size.
Really, the tiles should be centered in the middle of
the screen. (Just like when tiling a bathroom floor,
tiles should start in the center of the room.)
This commit reworks the math to make that happen.

Commit 4f2bb583bf started to use a clutter_threads_add_repaint_func_full
callback instead of connecting to the stage's paint signal.
The callback has to return TRUE if it wants to be called again, so fix that
as we want to call it for every frame (otherwise apps supporting the WM SYNC
protocol will stop drawing).

Doing so causes useless full stage redraws and breaks culling
as clutter cannot know how the signal handler affects painting.
So use clutter_threads_add_repaint_func_full with the
CLUTTER_REPAINT_FLAGS_POST_PAINT flag instead.

gnome-shell shouldn't announce to the session manager it's
"ready" until it's fully initialized. It currently tells
the session manager it's ready as soon as it hits the main
loop. This causes nautilus in classic mode to start before
we have workspaces initialized.

During compositor grabs, all global keybindings that don't go
through mutter's keybinding system are blocked. To allow other
processes to make use of it, gnome-shell will expose a simple
grab API on DBus; for this, add API to grab key combos directly
instead of parsing accelerators stored in GSettings.

There is currently code to try to fill gradients in a
hardware native format, using #ifdefs. That optimization is
unimportant since gradients only use 2 byte buffers. It's
also incorrect because it's getting the channel order wrong
at buffer initialization time.
This commit drops the ifdefs for clarity and fixes the
channel order.

meta_screen_get_monitor_for_rect will return the monitor that
a given rect belongs in (choosing the "best" monitor based on
overlap, if there are overlapping monitors).
It doesn't work with 0x0 rects, though.
This commit fixes that.

meta_window_is_remote compares a cached copy of the system hostname
with the hostname of the client window
(as presented by the WM_CLIENT_MACHINE property).
Of course, the system hostname can change at any time, so caching
it is wrong. Also, the WM_CLIENT_MACHINE property won't necessarily
change when the system hostname changes, so comparing it with the
new system hostname is wrong, too.
This commit makes the code call gethostname() at the time
WM_CLIENT_MACHINE is set, check whether it's remote then, and cache
that value, rather than comparing potentially out of sync hostnames
later.

Background handling in GNOME is very roundabout at the moment.
gnome-settings-daemon uses gnome-desktop to read the background from
disk into a screen-sized pixmap. It then sets the XID of that pixmap
on the _XROOTPMAP_ID root window property.
mutter puts that pixmap into a texture/actor which gnome-shell then
uses.
Having the gnome-settings-daemon detour from disk to screen means we
can't easily let the compositor handle transition effects when
switching backgrounds. Also, having the background actor be
per-screen instead of per-monitor means we may have oversized
textures in certain multihead setups.
This commit changes mutter to read backgrounds from disk itself, and
it changes backgrounds to be per-monitor.
This way background handling/compositing is left to the compositor.

actor_is_untransformed is a function meta-window-group uses to determine
if an actor is relatively pixel aligned and not contorted. It then
returns the coordinates of the actor.
In a subsequent commit will need the function in a different file, so
this commit separates it out.

Window menus use the first key combination for a binding to show the
acceleration, so the list must be in the right configured order, which
is the opposite of what's built by g_slist_prepend()

Now that the background actor is reactive, this means that
clicks on the window group part of the stage, even when they're
on an X window, will be registered as the background actor, as
all of the other children of the group aren't reactive. This can
happen when a plugin takes a modal grab, for instance.

The guard window is effectively the background window, as it sits
in between live windows and minimized windows. This gives us a nice
easy place to allow users to allow users to right-click or long-press
on the wallpaper.
