7e0087304b Add meta_window_is_skip_taskbar

consider windows with this hint in its overview thunbnails.

20b02e738c Make MUTTER_DEBUG_XINERAMA override active Xinerama
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.

a69ce37546 Unminimize windows passed to meta_workspace_activate_with_focus()
Unminimize minimized windows passed to meta_workspace_activate_with_focus()
by calling meta_window_activate() on them instead of meta_window_focus()
and meta_window_raise(). This fix makes sense because for the existing
usage inside Mutter meta_workspace_activate_with_focus() is never called
on a minimized window and for calls from outside Mutter there is no
point in focusing a minimized window without unminimizing it first.

Add a doc comment to meta_workspace_activate_with_focus().

7b0ba87b24 Fix custom-alt-tabs for single-handling of key events
The changes to enforce single handling of all key events were breaking
custom-alt-tab keypress handlers, since that code was assuming that
key event would get to process_tab_grab(), and then maybe to
process_event() and then to the plugin's xevent_filter to detect a
key release.

We centeralize all of this handling into process_tab_grab() and either

 - Invoke a custom handler for the key press
 - Select the current window on modifier release by calling a  new
   pseudo-binding "tab_popup_select"
 - Cancel the grab on an unbound key by calling a new pseudo-binding
   "tab_popup_cancel"

mutter_plugin_begin_modal() and mutter_plugin_begin_modal() allow putting

 - All keyboard and mouse events go exclusively to the plugin

mutter-plugin.[ch]: Add public API

mutter-plugin-manager.c: When reloading plugins, make sure none of them
  are modal at that moment, and if so force-unmodal them.

  events exclusively to the compositor.

d58c9a57c6 Avoid accessing freed memory when being replaced
If we are replaced via the window manager selection, then we close
the MetaDisplay before meta_finalize() runs. We should be careful
not to try to close the display again (and access already freed

01581dc61c [MetaWindow]: Always notify on title property change
The previous notification code was attempting to use the "modified"
boolean returned from set_title_text, but "that boolean doesn't mean
what you think it means".  It actually means "I truncated the title".

Just always notify, it's far simpler than trying to compute
when we don't need to, and callers can compress if they really need
to.

mutter-window.c originally grew an #include "window-private.h" for

ae32ac86b4 Use correct timestamp for focus stealing prevention
When window initially maps, use the more recent of NET_WM_USER_TIME and
startup notification timestamps to compare against last known user action to
decide whether to focus the window or not. Once we show the window, clear
the initial_timestamp_set flag, so the startup notification timestamp is not
taken into account again.

15376957f7 Don't allow override-redirect windows to be META_WINDOW_NORMAL
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.

239b39cf52 Pass through all scroll events to compositor
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;

6726fcd25d Simplify relationship between mapping and visibility
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.)

9244f0f113 Move window repair and reshape to a paint function
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.

bc9a2cc92a Don't move hidden windows to the desktop layer
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.

2c17ef4803 Emit signals when workspaces are added, removed or switched
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.

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

fd27647440 Don't read most properties for override-redirect windows
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.
