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
Reported by Patryk Zawadzki
http://bugzilla.gnome.org/show_bug.cgi?id=587975
* 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.
http://bugzilla.gnome.org/show_bug.cgi?id=587251
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;

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()

Separate code related to creating the gaussian-blurred shadow texture

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.

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

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.

With MetaStackTracker, it's no longer necessary to XQueryTree to
get a reasonably-up-to-date view of the server stacking order.

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.
http://bugzilla.gnome.org/show_bug.cgi?id=585984
In order to properly track the stacking order for override-redirect
windows, move meta_compositor_sync_stack() call into MetaStackTracker.
In the new location, we sync the stack as a before-redraw idle function,
rather then using the freeze-thaw facilities of MetaStack. This is
simpler, and also properly compresses multiple stack changes on
notifications received from the X server.
http://bugzilla.gnome.org/show_bug.cgi?id=585984
Wedging override-redirect windows into the constraint code in stack.c
results in Mutter getting confused about the stacking order of
these windows with respect to other windows, and may also in some
cases cause Mutter to restack override-redirect windows.
core/stack-tracker.c core/stack-tracker.h: MetaStackTracker - combine
events received from the X server with local changes we have made
to come up with the best possible idea of what the stacking order
is at any one point in time.
core/screen.c core/screen-private.h: Create a MetaStackTracker for
the screen.
core/display.c: Feed relevant events to MetaStackTracker
core/frame.c core/screen.c core/stack.c: When we make changes to the

in MetaStackTracker so we have the information without waiting
for a round-trip.

Override-redirect windows should not be moved or resized by the
window manager.
- Mark override-redirect windows as already placed to avoid
placing them when first shown.
- Don't move-resize newly created override-redirect MetaWindow
- Don't queue a resize on override-redirect windows when reading
their WM_TRANSIENT_FOR hint.
- Add g_return_if_fail (!window->override_redirect) to catch
unexpected code paths that might result in override-redirect
windows being moved or resized.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Normally a window that is "on all workspaces", is also on a particular
workspace (to deal with being unstuck.) This is pointless for
override-redirect windows.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Don't include override-redirect windows when iterating the windows
in the screen. We don't need them for any of the current uses:
- Queueing redraws and resizes on managed windows
- Checking which windows should be added to a new workspace
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Don't include override-redirect windows in the list return by
meta_display_list_windows(), since we almost never want to handle
them when considering "all window" for the display. Add a separate
meta_display_list_all_windows() that includes override-redirect
windows.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
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.

If a property has a reload function, but the standard property-fetching

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.

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

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.

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.

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()

want.
Also add meta_screen_destroy_tab_popup()/_destroy_workspace_popup()

Using G_MODULE_BIND_LOCAL causes problems for introspecting plugins,
since introspected symbols need to be globally available. And in

Always compile the default keybindings into Metacity, and if we
fail to retrieve the values from GConf, use the compiled-in

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

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.)

To guard against CompositeNameWindowPixmap failing, just use an
error trap. Previous code used:
GrabServer/GetWindowAttributes/CompositeNameWindowPixmap/UngrabServer

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.

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.
