We were freeing the description string in dispose and not setting it to NULL,
thus leaving around a dangling pointer for the duration of the disposal.
This commit moves the free into the finalize vfuction, where it belongs.
Many override-redirect windows (including the Metacity UI windows!)
will have NET_WM_WINDOW_TYPE_NORMAL set on them because of shared
code paths with normal windows in toolkits.
Some current Compositor plugins (default plugin and gnome-shell)
check type == NORMAL to determine if to run effects. While fixing
such plugins to also check if the window is override-redirect is
posisble, it seems cleanest to simply not allow any of the decorated
window types to be set on an override-redirect window and to force
these types to META_WINDOW_OVERRIDE_OTHER. This will prevent other
similar problems from showing up in the future.

When calculating maximum permissible size of our frame window, we need to
avoid an overflow if the application set its max size hint to INT_MAX.
http://bugzilla.gnome.org/show_bug.cgi?id=590627
As a sideffect of commit a576f7a1ea, override
redirect windows of type _NET_WM_WINDOW_TYPE_NORMAL do not have their
features recalculated during MetaWindow construction (same as regular
windows of type _NET_WM_WINDOW_TYPE_NORMAL), so we need to set the initial
values accordingly.
Although the spec designates some window types as typically used for
override redirect windows, it does not prohibit the use of these with
managed windows, so we should not abort if we encounter one of these.

As with other events, we want to pass through scroll events (button 4/5 presses)
to the compositor, whether or not they are associated with a particular MetaWindow;
do this by simply falling through to the normal code path instead of
separately delivering the events to the compositor.
http://bugzilla.gnome.org/show_bug.cgi?id=588232
Setting the size of the texture causes the minimum and preferred width and
height values to be fixed at the set value. The normal requisition functions
of ClutterTexture will already report the size of the texture pixmap as the
natural size, but also allow scaling down as needed if less space is
available. We don't need that here, but we want to allow someone to make
a ClutterClone of the texture actor.
With recent changes, Clutter no longer sets up the viewport correctly,
unless it receives ConfigureNotify events. If there is a plugin with
an xevent_filter function, then it's that plugins responsibility to pass
the event to Clutter if it doesn't want it. If there is no plugin,
or the plugin doesn't have an xevent_filter function, then we should
call clutter_x11_handle_event() ourselves.

When a windows contents or shape changes, we schedule a redraw
with clutter_actor_queue_redraw(); we need to queue the redraw
on the shaped texture rather than on the window actor to support
cloning of just the shaped texture without the shadow: that
is, the shaped is what is really changing and it may be
visible via a clone even if the MutterWindow itself is not
visible.

MetaPreview is only built into libmutter-private, and not included in
the mutter executable. Linking mutter against libmutter-private was
inadvertently added when the introspection build process was set up,
but isn't actually needed, and if -Wl,-as-needed is added during the
build process, then the libmutter-private dependency will be skipped.
* Don't link mutter (or the test programs) against libmutter-private
* Exclude meta-preview.h from the set of headers we feed into the
introspection build process

* Make generation of the .gir file work for srcdir != builddir
* Add files to CLEANFILES as needed
* Don't distribute the generated file mutter.schemas
When we are painting a stack of 5-10 maximized windows, the
standard bottom-to-top method of drawing every actor results
in a tremendous amount of overdraw and can easily max out
the available memory bandwidth on a low-end* graphics chipset.
It's even worse if window textures are being accessed over
the AGP bus.
When we have opaque windows, we can go ahead and compute visibility
ourselves (in classic X-server fashion) and use that information to
restrict drawing obscured actors.
* Add MutterWindowGroup - a ClutterGroup subclass with logic
for figuring out obscured regions.
* Add mutter_window_get_obscured_region() to get the region
obscured by that window.
* Add mutter_shaped_texture_set_clip_region() to hint
a clip region to the painting code; this is set based on
the computed visible region of MutterWindowGroup.
* Add tidy_texture_frame_set_needs_paint() to hint that the
paint can be skipped entirely; this is used when we detect
that the window shadow is entirely obscured.

If we are starting on something other than the first workspace,
meta_compositor_switch_workspace() will be called before
meta_compositor_manage_screen(); guard against that.
Previously, changes to the visibility of a window could be indicated
by meta_compositor_map_window(), meta_compositor_unminimize_window(),
meta_compositor_set_window_hidden(), etc, with the exact behavior
depending on the 'live_hidden_windows' preference.
Simplify this so that visibility is controlled by:
meta_compositor_show_window()
meta_compositor_hide_window()
With an 'effect' parameter provided to indicate the appropriate
effect (CREATE/UNMINIMIZE/MINIMIZE/DESTROY/NONE.)
The map state of the window is signalled separately by:
meta_compositor_map_window()
meta_compositor_unmap_window()
And is used only to control resource handling.
Other changes:
* The desired effect on show/hide is explicitly stored in
MetaWindow, avoiding the need for the was_minimized flag.
At idle, once we calculate the window state, we pass the
effect to the compositor if it matches the new window
state, and then clear the effect to start over for future
map state changes.
* meta_compositor_switch_workspace() is called before any windows
are hidden or shown, allowing the compositor to avoid hiding
or showing an effect for windows involved in the switch.
http://bugzilla.gnome.org/show_bug.cgi?id=582341
* Handling of post-effect cleanups for MutterWindow are
simplified - instead of trying to do different things based
on the individual needs of different effects, we just wait until
all effects complete and sync the window state to what it
should be.
* On unmap, once we destroy the pixmap, we tell ClutterX11Pixmap
that we've done so, so it can clean up and unbind. (The
unbinding doesn't seem to be working properly because of
ClutterGLXPixmap or video driver issues.)
http://bugzilla.gnome.org/show_bug.cgi?id=587251
Clean up mutter_window_effect_in_progress() by removing the
include_destroy parameter which was used only in one place that
could be easily done otherwise. (There was another use in
mutter_window_sync_actor_position() that had no point and looked
unintended.)
http://bugzilla.gnome.org/show_bug.cgi?id=587251
Add a paint function that checks all windows for repair and
shape updates; this:
- simplifies the logic for when a window needs to be repaired
- avoids duplicate work when we get multiple damage effects
- avoids the need to look ahead in the event queue
Instead of relying on repair to implicitly resize the
MutterWindow actor, set the size explicitly when the core
code updates the geometry. (This is needed because we haven't
repaired yet when we start an animation, and the animation
may depend on the size to, e.g., rescale from the center.)
Because the core geometry update happens before we start
maximize/unmaximize effects we need to work around this by
passing both the old and new geometry to the compositor.

Putting hidden windows in the desktop layer is pointless - in
the desktop layer isn't necessary below all visible windows,
and we are hiding the windows by other means. And the movement
isn't reliable because nothing sets stack->needs_relayer, so
windows can get stuck in the desktop layer after being
rehidden.

compositor.c: Move MutterWindow code to mutter-window.c;
rename map_win() to mutter_window_map(), etc.
mutter-window-private.h: New private header file for
MutterWindow functions used internally to the compositor.
compositor-mutter.h: Move MutterWindow declarations to
mutter-window.h; move a couple of private functions to
compositor-private.h
compositor-private.h: Move MetaCompScreen declaration to here:
Conceptually it's private to compositor.c, but MutterWindow
manipulates some of the lists directly for now.
mutter-plugin.c compositor.c: Don't call mutter_window_effect_completed()
for MUTTER_PLUGIN_SWITCH_WORKSPACE, but use a new
mutter_switch_workspace_completed(), since the window is
just used to identify a screen.
http://bugzilla.gnome.org/show_bug.cgi?id=587251
Separate code related to creating the gaussian-blurred shadow texture
into a separate file.
Move the definition of MetaCompositor into a compositor-private.h
so that the shadow code can cache the source in the compositor
structure.
http://bugzilla.gnome.org/show_bug.cgi?id=587251
The patch adds GLib marshalling code to Mutter, since it's required for the "workspace-switched" signal.
The definition of MetaMotionDirection enum is moved to common.h since it's now used in workspace.c.
A little cleaning is done in workspace.c:meta_workspace_activate_with_focus(), where compositor-specific code is merged with the rest of the function (required to emit signal), removing #ifdefs.
Remove a number of functions that were either entirely unimplemented
or had empty implementations for the Clutter-compositor.
meta_compositor_begin_move()
meta_compositor_update_move()
meta_compositor_end_move()
meta_compositor_set_active_window()
meta_compositor_free_window()

Now that we only have one compositor, there's no reason to access the
compositor functions through a vtable. Remove the MetaCompositor virtualization
and make the clutter code implement the meta_compositor_* functions
directly.
Move the checks for the compositor being NULL from the vtable wrappers
to the calling code (most of them were already there, so just a few
needed to be added)
Note: the compositor is actually hard-coded on at the moment and the plan
is to remove the non-composited code entirely, so the checks are
added only to keep things neat: they have no practical effect.

Mutter is a Clutter-based compositing manager. So, remove the code for
the XRender-based compositor, and make it mandatory to have XComposite,
XRender and Clutter.
Run-time support for non-composited operation is left for now.
* src/compositor/mutter/: Move files from this subdirectory into
the main compositor/ directory.
* compositor/compositor-xrender.ccompositor/compositor-xrender.h:
Remove
* include/compositor-clutter.h: Remove this stray file, it had been
replaced with compositor-mutter.h some time back.

Since the stack passed to the compositor now accurately reflects
the X stacking order, we need to treat hidden windows (which are
at the bottom of the X stacking order) specially - when the
compositor stacking order is synced, try to keep animating hidden
actors in their old positions in the stack.
http://bugzilla.gnome.org/show_bug.cgi?id=585984
With MetaStackTracker, it's no longer necessary to XQueryTree to
get a reasonably-up-to-date view of the server stacking order.
Add some comments explaining unclear aspects of
raise_window_relative_to_managed_windows() and with future possible
improvements.
http://bugzilla.gnome.org/show_bug.cgi?id=585984
Don't add override-redirect windows to MetaStack; we shouldn't
be restacking them.
Since we *aren't* stacking the override-redirect windows, we need to
be careful that to ignore them when looking for the top managed
window.
