src/core does some things depending on window->mapped, but since we now
leave the window mapped for hidden windows we might get some wrong
descisions.
Also instead of calling meta_window_show when in meta_window_hide for
the case that the window isn't currently mapped, we now simply
XMapWindow.
It's more awkward and error prone, considering plugin ininteractions, to simply
show/hide the actors of hidden windows, and it seems to be more reliable to
reparent them to a hidden group instead.
We can't easily use a metacity layer to hide windows as that means we
loose our original stacking position. (Metacity's stack positions are
only valid within a single layer) We now have a "guard window" per
screen that is a fullscreen override redirect that is lowered to the
bottom of the stack. Hidden windows now remain in their original layer
so the stacking position remains valid, but all hidden windows get
XRestacked under the guard window.
A new compositor hook is also added to inform it when a window becomes
hidden/unhidded, this lets us map/unmap the corresponding actor.

Calling clutter_actor_show_all() on the stage and overlay_group breaks
the ability for plugins to create initially hidden actors. Call
clutter_actor_show() instead.
If a mutter plugin name (in GConf, or more likely on the command line)
looks like an absolute path, use that path directly rather than
looking for the plugin in the plugins directory.
src/core/main.c: Add --mutter-plugins argument (overrides GConf value)
src/core/prefs.c src/include/prefs.h: Add meta_prefs_override_clutter_plugins()
to set a value for clutter_plugins that overrides the value from GConf
Remove a "got here" leftover, remove unnecessary trailing \n when
calling g_message(), include g_module_error() in the output when
loading a module fails.
If --disable-static is passed to configure, then .a files won't be built
or installed. Make removing them in install-exec-hook not fatal if they
don't exist.
The clutter_plugins schema key did not define the type of the
elements inside the list, thus making gconftool choke when installing
the Metacity schemas.
Since clutter_plugins is a list of strings, the trivial fix is
to add the corresponding <list_type> element to the schema XML.
We need to be getting ConfigureNotify events for these, so we can respond
to changes in position of these windows. We cannot add this to windows
Metacity manages, as this makes it got mental.
ClutterActors for hidden windows (such windows on different than active
workspaces and windows that are minimized) are available, and reflect the
actual state of the window. This is intended for use in task-switchers etc.
This feature is disabled by default (due to increased demand on resources),
and can be enabled through the metacity/general/live_hidden_windows gconf key.
A trivial sample window switcher is included in the scratch plugin (activated
by clicking on the slide out panel).
