We want to remove a bunch of auxilliary duties from the MetaWindowActor
and MetaSurfaceActor, including some details of how culling is done.
Move the unobscured region culling code to the MetaShapedTexture, which
helps the actor become "more independent".

When we traversed down to reset the culling state, previously we
would just skip any actors that wanted culling. In order to properly
reset the unobscured_region before painting, we need to traverse down
to these places as well. Do this by calling cull_out with NULL regions
for both arguments, and adapt existing cull_out implementations to
match.

The code that prevents the creation of multiple MonitorInfos for clones
wasn't working due to using the wrong index when getting the already
created info so fix that to use the correct one.

Ever since the change to create the output window synchronously at startup,
there hasn't been any time where somebody could set a stage region the
output window was ready, so this was effectively dead code.

I know it's confusing with the triple negative, but unredirected is how
we track it elsewhere: we have an 'unredirected' flag, and 'should_unredirect'.

Using a full InputOutput window causes us to make a full Wayland surface
for it, and go through the X server. As the goal of the guard window is
a window for us to stack minimized windows under so we can prevent them
from getting input, it makes sense to use an InputOnly window here.
We currently ignore the unobscured region when we have mapped clones in
meta_window_actor_process_damage and meta_window_actor_damage_all but
use it unconditionally when computing the paint volume.
This is wrong. We should ignore it there as well or we will end up with
empty clones if the cloned window is completly obscured
(like the tray icons in gnome-shell).

Make MetaWindowActor chain up to the generic default MetaCullable
implementation, and remove the helper methods for MetaSurfaceActor
and MetaShapedTexture.
We need to set the number of components on the CoglTextureRectangle to
prevent wasting too much GPU memory. As we need to do this before we call
cogl_texture_set_region, just remove the meta_texture_rectangle_new wrapper,
and make callers call cogl_texture_rectangle_new_with_size directly.
When GDK sends an unmaximize _NET_WM_STATE ClientMessage, it tells us to remove
the _NET_WM_STATE_MAXIMIZED_HORZ and _NET_WM_STATE_MAXIMIZED_VERT states. Before
this time, it would independently call:
meta_window_unmaximize (window, META_MAXIMIZE_HORIZONTAL);
meta_window_unmaximize (window, META_MAXIMIZE_VERTICAL);
Which, besides being foolishly inefficient, would also mess up our saved_rect
tracking, causing the window to only look like it was unmaximized vertically.
Make this code more intelligent, so it causes us to unmaximize in one call.

This grab was added in commit caf43a123fhttps://bugzilla.gnome.org/show_bug.cgi?id=381127
to minimize window flickering when switching workspaces.
While this grab is held, some signals are emitted to the shell,
which can lead to deadlocks (reproduced under Mali binary OpenGLESv2
drivers).
Now that we are a compositing window manager, we do not have to
worry about flickers, this grab should no longer be necessary.

Under some circumstances, for example when the display controller driver
doesn't report back the correct EDID, or under VirtualBox, Mutter
returns suboptimal strings for an output display name, leading to funny
labels like 'Unknown 0"', or '(null) 0"' in the Settings panel.
This commit improves our heuristic in three ways:
- we now avoid putting inches in the display name if either dimension is
zero
- we use the vendor name in case we're not able to lookup its PnP id
from the database. Previously we would have passed over '(null)'
- as a special edge-case, when neither inches nor vendor are known, we
use the string 'Unknown Display'
Finally, we make the combined vendor + inches string translatable, as
different languages might want to move the size part of the string to a
position different than the end.
