meta_window_group_paint tries to carefully figure out which parts of the
scene it can avoid painting. One area it avoids painting is the region of
the screen occupied by an unredirected window (if there's one present).
When subtracting from the visible region, it gets the coordinate spaces
confused, and ends up subtracting the area at the wrong offset. Fix this
by translating the rectangle subtracted from the visible region.

When changing the overlay-key setting, the change only takes effect
on restart - there are actually two bugs involved:
(1) the test whether the key has changed is located in the
else part of a test for string settings (and overlay-key happens
to be a string settings ...)
(2) with (1) fixed, a change signal is emitted, which triggers a
reload of all keybindings - unfortunately, the actual value
of overlay-key is only read on startup, so the key is reloaded
using the old value
Fix both issues by replacing the custom handling of the overlay-key
with the regular handling of string preferences.

Instead of getting the x/y of the MetaBackgroundActor with respect to the
parent, use the same logic that we do for windows, fixing the case
where there is a more complex transformation involved.

Currently when the window group is moved, the visible region set
on the background actor no longer matches the actually visible
region, resulting in flickering around window actors.
Fix by translating the visible region with the window group.

When we consider tiling a special case of maximization, it makes
more sense to always unmaximize to the normal state rather than
restoring a previous tile state.

Currently we decide whether a modal dialog should be attached or not
when mapping it, i.e. we don't pick up preference changes that happen
while the dialog is up. It's not really a big deal given that modal
dialogs are usually transitory, but it's easy enough to add a bit of
extra polish ...
