The metacity core is now directly aware of override redirect windows.
- They get MetaWindows like normal windows, so mutter no longer need to special
case them. The net wm types applicable to override redirects are also
recognised.
- The original positioning/stacking semantics of metacity with respect to OR
windows are maintained, but now it's easier to synchronize the stacking
between the core and mutter.
- mutter no longer needs to manualy track UnmapNotify, MapNotify,
ReparentNotify, CreateNotify and DestroyNotify events; instead map, unmap,
add and remove events can now be consistently delivered via the
MetaCompositor callbacks.
Since this is the most common cause of performance issues, this makes it
clearer when GLX TFP isn't being used. Note, there was a corresponding
fix to clutter_glx_texture_pixmap_using_extension() committed last week
as r3559 in the 0.8 branch.
When multiple events are generated from a single event (for example,
when a motion event generates an enter/leave pair), events accumulate
in the clutter event queue if the clutter event source is not running.
Add a simple event source that checks clutter_events_pending() and
dispatches events as necessary.
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.
