When windows get redirected off screen, all that gets left behind
is black. We don't want to flicker black at startup, though.
This commit maps the overlay window early, before redirecting
toplevels, so they end up getting snapshotted onto the background
pixmap of the overlay window when the overlay window is mapped.

Send a _NET_WM_FRAME_DRAWN for each newly created window, as required
by the specification. This avoids a race where a window might be created
frozen but already unfrozen by the time we first see fetch the
counter value.
Remove a duplicate call to meta_compositor_set_updates_frozen() which
was called before the MetaWindowActor is created and hence did nothing.

mutter currently only filters the overlay key through the shell
when there is a grab operation and that grab operation belongs to the
shell (because the shell is pushModal'd). This means the shell can't
filter out overlay key press events events at startup (since the shell
isn't normally modal).
This commit changes the code to always run the shell filtering code,
even when the shell is not modal.

The background vignette currently fits itself to the painted
texture, instead of the monitor. This causes some very
wrong looking drawing for backgrounds that don't fill the screen.
This commit reworks the vignette shader code to be clearer, more
correct, and parameterized so that it knows how to scale and
position the vignette.

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.
