Changing the number of workspaces via an external pager relies on the gconf
key; if a plugin adds or removes workspaces on the fly, we can get into a
situation when the stale number stored by the preferences matches the new
number requested by the pager, in which case the pager request becomes a nop.
This commit ensures that when the meta_screen_append_new_workspace() or
meta_screen_remove_workspace() functions are called, the stored value is
updated accordingly.

There was a problem where if, for example, a restack was triggered
out of a clutter event handler, then after Clutter processed the
events, it would proceed immmediately on to repaint the stage without
ever returning control to the GLib main loop. So even though we
had an idle handler installed with a higher priority than the
Clutter stage repainting the clutter stage repainting would happen
first and we'd get a wrong frame.
Fix this by introducing the idea of "later functions", which abstract
the idea of "doing something later" away from g_idle_add() and use
a combination of GLib idle functions and Clutter "repaint functions"
to get our callbacks triggered at the right time, even when they
are installed from a clutter event handler.
https://bugzilla.gnome.org/show_bug.cgi?id=596334
This also resolve a FIXME where MUTTER_PRIORITY_BEFORE_REDRAW
could starve stage repainting.
It seems a bit cleaner to make the MUTTER_DEBUG_XINERAMA variable
that sets up fake Xinerama take effect even if Xinerama is active;
this means we don't count on Xinerama (or Xrandr if we switch tot
that) special casing the case of one monitor.

It's useful for plugins to be able to get access to the
startup-notification data that Mutter already has. Add
an accessor and change signal when recieve an event.
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
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.
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.

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
stacking order or add windows, record those changes immediatley
in MetaStackTracker so we have the information without waiting
for a round-trip.
include/ui.h ui/ui.c: meta_ui_create_frame_window add a return value
for the X request serial used to create the window.
http://bugzilla.gnome.org/show_bug.cgi?id=585984
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
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.
Also, use MetaWindows as the tab_popup keys rather than using (X) Windows
and then having to map back and forth everywhere, which is silly since
we never actually want the X Window.
http://bugzilla.gnome.org/show_bug.cgi?id=580917
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.
http://bugzilla.gnome.org/show_bug.cgi?id=580917
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.
http://bugzilla.gnome.org/show_bug.cgi?id=563047
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.
Add a keybinding (defaulting to <Control><Shift><Alt>r) to record
a screencast of the session. This isn't hooked up to anything in
metacity itself, but a plugin can connect to a signal on MetaScreen.
keybindings.c all-keybindings.h: Add the keybinding
screen.c: Add a ::toggle-recording signal
http://bugzilla.gnome.org/show_bug.cgi?id=575290
Expose restacking and a window's stack layer to allow a compositor
to insert elements into the window stack in the right location.
(See Bug 571827 – hide panel when screensaver is active)
src/core/stack.h src/include/common.h: Move MetaStackLayer to
a public header.
src/core/screen.c src/core/screen-private.h src/core/stack.c:
Add a ::restacked signal emitted after we finish restracking.
src/core/window.h src/include/window.h: Add meta_window_get_layer()
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.
src/core/screen.c src/core/screen-private.h src/include/screen.h:
Make MetaScreen a GObject.
src/core/workspace.c src/core/workspace-private.h src/include/workspace.h:
Make MetaWorkspace a GObject. Rename meta_workspace_free() to
meta_workspace_remove().
http://bugzilla.gnome.org/show_bug.cgi?id=561297
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.
missing files in preview commit (TODO: rebase -i and squash this later)
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).
