We currently resync the stacking order of the two key frames
every iteration of the animation. This is costly and unnecessary.
This commit ensures they're stacked properly up front and doesn't
touch them after that.

Right now we take a still frame of the desktop before showing the
start up animation. This gives us an animation over what was
there before startup.
That's not actually desirable when restarting the shell. We don't
want to animate over undecorated windows, we really want to animate
over the noise texture.
This commit drops the still frames in favor of the noise texture.

Previously, we would create one StBin per monitor, but each was positioned
at 0,0 and sized as the screen, so they would overlap and draw the box shadows
on top of the other backgrounds.
Instead, we need to size appropriately the bin, and then we need to position
the actual MetaBacgroundActor at 0,0, so add a flag to BackgroundManager
for this.
Also, get rid of MetaBackgroundGroup, they do nothing because the screenshield
is not a descendant of the MetaWindowGroup and because the widget in between
blocks the propagation of the visible region. At the same time, use a
widget, not a bin, because StBin requires you to set .child, not call add_child().

The key was removed from gsettings-desktop-schemas, GNOME should
always draw a background: the key existed to support xsetroot, but
we no longer read the _XROOTPMAP_ID.

gnome-desktop's background drawing code supports an
XML format for presenting backgrounds based on time of day,
monitor geometry, etc. Now that we don't use gnome-desktop for drawing the
background, we need to implement that support ourselves to maintain
feature parity.
This commit implements that.

This commit updates the code to use mutter's new background
api, and changes the shell's startup animation to be closer
to the mockups.
