Skipping handling of properties for override redirect windows has
two advantages: first it reduces the amount of work needed to get
an override-redirect window (menu, tooltip, drag icon) onto the
screen. But more importantly, it reduces the number of code-paths
for an override-redirect to get into some code portion where it
isn't expected.
* Integrate the list of properties we load initially with the
list of property hooks; this avoids having two separate lists
that we have to keep in sync.
* Add a flag to MetaWindowPropHooks to indicate whether the
property should be handled for override-redirect windows;
currently we load a) properties that identify the window -
useful for debugging purposes b) WM_TRANSIENT_FOR (could be
used to associate menus with toplevels.)
* For properties that aren't always loaded through window-props.c,
add !window->override checks to places that trigger loading,
and add g_return_if_fail(!window->override) to the load
functions as a double-check.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Add g_return_if_fail() to check that window-management functions like
meta_window_maximize() aren't called on override-redirect windows.
This reveals that were were "unminimizing" override-redirect windows
when adding them; avoid doing that.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
If a property has a reload function, but the standard property-fetching
mechanism isn't used (hooks->type == META_PROP_VALUE_INVALID), then the
a logic error (introduced in January) caused the hook to never be run.
This meant that changes to struts and icons weren't noticed.
Same as: http://bugzilla.gnome.org/show_bug.cgi?id=572573
The fix here is different in detail from that applied to Metacity, but
similar in spirit.
http://bugzilla.gnome.org/show_bug.cgi?id=585980
On subsequent changes, if there is a NET_WM_USER_TIME_WINDOW, then
read the property from that rather than from the main window.
(Fix an accidental regression: the right Window was being computed
but no longer passed in.)

This reverts commit 16d49695ad.
If we want an actor to go away deterministically, we should call
clutter_actor_destroy(); using unparent instead a) may result
leaks through cyclic ref counts, and b) will delay the deallocation
of the window texture in a garbage collected environment until
the next garbage collection, causing much greater transient use
of memory.
http://bugzilla.gnome.org/show_bug.cgi?id=580520
info->pending_input_region needed to be destroyed in
mutter_set_stage_input_region() before it was set to something
else or before it was reset to be full screen (region == None).
Set the initial input area to an empty region by
setting info->pending_input_region to an empty region by default
and setting it to None or a new region if a new input region is
specified.
Remove show_overlay_window() function that was used to set an empty
input region on start-up, and uses a call to do_set_stage_input_region()
with info->pending_input_region as an argument instead.
When we add a window and it gets hidden as the first thing, we need
to show not just the frame window, but also the window itself.
Otherwise when the window subsequently becomes visible, it will
just be an empty frame.
Add helper functions to reduce current code duplication and avoid
adding more.

Code:
All references in the code not related to themes, keybindings, or
GConf were changed from 'metacity' to 'mutter'. This includes, among other
things, strings, comments, the atoms used in the message protocol, and
the envvars used for debugging. The GConf schema file was reduced to
the 3 settings new to mutter.
The overall version was brought up to 2.27 to match current gnome.
Structure:
All files named '*metacity*' were renamed '*mutter*' with appropriate
changes in the automake system. Files removed are
doc/creating_themes, src/themes, doc/metacity-theme.dtd,
metacity.doap. These files will eventually end up in an external
gnome-wm-data module.
Installation location:
On the filesystem the mutter-plugindir was change from
$(libdir)/metacity/plugins/clutter to just $(libdir)/mutter/plugins.
The mutter-plugins.pc.in reflects these changes.
Note:
mutter.desktop.in and mutter-wm.desktop both continue to have
X-GNOME-WMSettingsModule=metacity set. This allows
gnome-control-center to continue using libmetacity.so for
configuration. This is fine since most the general keybindings and wm
settings are being read from /apps/metacity/* in gconf.
Change #define _XOPEN_SOURCE 500 to 600 in compositor-xrender.c to
avoid a bad interaction with -xc99 on Solaris.
Remove unneeded #define in compositor-mutter.c.

It doesn't make sense to allow the window texture to be sliced,
but not allow the mask texture to be sliced. So, we should either
set 'disable-slicing' for the texture actor or not pass NO_SLICING when
creating the mask texture.
While slicing currently results in only the first layer being shown,
disabling slicing entirely would break windows larger than the texture
size limit. It would be straightforward to support multitexturing of
sliced textures in Cogl when all the textures are identically sized
and sliced identically, if it became a priority.

If the input region has been shaped, then clutter needs to

Also, use MetaWindows as the tab_popup keys rather than using (X) Windows

Rather than trying to reverse-engineer what kind of tab/workspace
popup to create from within meta_display_begin_grab_op(), just create
the popup directly from do_choose_window()/handle_workspace_switch()
after completing the grab, since they already know which kind they
want.
Also add meta_screen_destroy_tab_popup()/_destroy_workspace_popup()
rather than having meta_display_end_grab_op() poke into MetaScreen's
internals itself.

Using G_MODULE_BIND_LOCAL causes problems for introspecting plugins,
since introspected symbols need to be globally available. And in
any case, trying to use linker features to prevent symbol conflicts
doesn't usually work out very well, it's better to just namespace
properly.

Add separate mutter_plugin_manager_load() and

Always compile the default keybindings into Metacity, and if we
fail to retrieve the values from GConf, use the compiled-in
value. This makes things more robust especially in an environment
like JHBuild where GConf-schema-installation may not work
correctly.
Also use these values for the no-GConf case, rather than
having a separate arrray and code path.

This patch adds the concept of a special key for WM operations, and
the default is Super_L, which on extended PC hardware is the
"Windows key". What we do is handle the special case of a press
and release of this key (without any other intervening keys).
Super_L+<key> should still be passed to applications. In the future
we may want to also take some of these keybindings (e.g. Super+TAB)
though.

Add sigals to MetaWorkspace to allow tracking when windows are added
and removed. Note that on window creation that these signals are fired
before the window setup is totally complete, so they need to be used
with some care. (For example, the compositor, if present, has not
been notified of the new window.)
http://bugzilla.gnome.org/show_bug.cgi?id=580025
To guard against CompositeNameWindowPixmap failing, just use an
error trap. Previous code used:
GrabServer/GetWindowAttributes/CompositeNameWindowPixmap/UngrabServer
To prevent BadMatch errors from !viewable, but didn't check the
return value of GetWindowAttributes and didn't check if an error
occured during the error trap. This way is more correct and more
efficient.

When the window being hidden/mimimized has focus, is modal, but is not on the
currently active workspace (e.g., during workspace switch before the new
focus window is activated), we must prevent focus being passed to the modal
window ancestor (otherwise the ancestor ends up being forcefully moved onto
the active workspace).
Creating the gard window when constructing MetaScreen causes the screen to
go black for the duration of Metacity startup which is uggly. We do not
actually need that window until we are ready to manage windows on the screen.
Make meta_window_get_icon_geometry() public, so that it can be used
to from plugins to animate windows minimizing to the correct
position.

The overlay window was created before the plugins are loaded. Because the
composite extension immediately maps the window, we ended blanking the screen
while plugins, etc., were loading. This commit reorganizes the code so that
the overlay window is only created just before we are ready to show the
stage.
The significant impact of this change is that plugins cannot manipulate the
overlay window during their initial loading, i.e., they cannot call the
input-region API (the plugin should hook into the "show" signal if it needs
to do anything of this sort).
The commit also removes the XClearArea() call on the overlay window that
seems to have served no real purpose.
In particular, make it so that we call meta_compositor_add_window() on
a new window before calling meta_compositor_sync_stack() to position
it. The list returned by mutter_plugin_get_windows() is only updated
by sync_stack(), but sync_stack() only pays attention to windows that
add_window() has already been called on. So without this change, a
newly-mapped window will not be returned by
mutter_plugin_get_windows() until after the *next* restacking.
http://bugzilla.openedhand.com/show_bug.cgi?id=1512
Once the window destruction is initiated, we can still manipulate our
MutterWindow with clutter API, but we can not longer use any X-based API,

Add 'hide_after_effect' flag to MutterWindowPrivate, tracking
whether the window needs to be hidden after all outstanding effects
finish.
Set or clear the flag as appropriate in clutter_cmp_set_window_hidden.
In mutter_window_effect_completed, if hide_after_effect is TRUE
and no other effects are in progress, hide the window.
When there is custom handler installed for the tab releavant tab function
we do not want to actually call it form inside of this function, only to
ensure that the grab is not released. The handler will get called in the
normal way in process_event(). Whoever installed the handler (and requested
the grab) also has to ensure the grab is released.
Requiring the compositor private object to be a GObject allows the
return value of meta_window_get_compositor_private() to be used
via gobject-introspection, since the type and memory management
can be determined.
This allows a reverse mapping from MetaWindow to MutterWindow.
- Change meta_window_get/set_compositor_private to use GObject
rather than void *
- Adapt code in compositor-mutter.c to match.
Now that Cogl has the material API we can use Cogl calls for
multi-texturing instead of directly calling GL.
The MutterShapedTexture actor keeps a handle to a material with the
right combine modes for combining the texture and the shape
mask. Before each paint it sets the layers of the material to be the
two textures.
A second material with different combine modes 1is also created if the
pixmap is 24 bit to implement the workaround from commit 72da8c57.
It seems that with the latest intel drivers when multi-texturing using an RGB
TFP texture, the texture is being setup internally as an RGBA texture, where
the alpha channel is mostly 0.0 so you only see a shimmer of the window. This
workaround forcibly defines the alpha channel as 1.0. Maybe there is some
clutter/cogl state that is interacting with this that is being overlooked,
but for now this seems to work. (Tested on i945 + DRI2)

Add (transfer none) annotations to mutter_window_get_texture()
and mutter_window_get_meta_window(), and while add doc comments,
actually add some docs as well.
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

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.

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.
