Instead of creating a new alarm each time we resize a window
interactively, create an alarm the first time we resize a window
and keep it around permanently until we unmanage the window.
Doing it this way will be useful when we allow the application to
spontaneously generate sync request updates to indicate
frames it is drawing.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Replace the unused meta_compositor_set_updates() with
a reversed-meaning meta_compositor_set_updates_frozen(), and use
it to implement freezing application window updates during
interactive resizing. This avoids drawing new areas of the window
with blank content before the application has a chance to repaint.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
meta_screen_resize calls meta_window_update_for_monitors_changed for all
windows including OR windows when the monitors change (or screen size).
This calls meta_window_move_between_rects for the window which attempts to
move the OR window by calling meta_window_move_resize.
meta_window_move_resize refuses to do anything on OR windows (just returns
for OR windows).
This causes a storm of assert messages when the screen
resolution changes while an OR window is visible.
(like the one gnome-control-center displays with the monitor name).
Fix that by not calling meta_window_update_for_monitors_changed for OR windows
and let the applications handle them by themselves.

- set GTK_STYLE_CLASS_TOOLTIP on the window, and use the same code of
GtkTooltip to paint it
- set GDK_WINDOW_TYPE_HINT_TOOLTIP and make the window non-resizable, so
it doesn't get an incorrect shadow from the WM
https://bugzilla.gnome.org/show_bug.cgi?id=692741
Since we're going to use the tooltip's rounded corners we need a little
bit more of margin (which wasn't a bad idea even with the frame).
Also, don't use GtkMisc for this anymore.
https://bugzilla.gnome.org/show_bug.cgi?id=692741
As the hash table no longer stores only window IDs, we should rename it so
that we make sure to check if something is actually a window before using it
as a window.

XInput 2.3 adds support for "barrier events", which let us know when
a pointer barrier has been hit, and when the pointer has stopped
hitting the barrier, and lets us "release" the barrier, temporarily
letting the pointer pass through the barrier. These features can be
combined to allow for certain pointer gestures, such as "pushing"
against the bottom of the screen, or stopping the pointer on monitor
edges while dragging slowly for increased edge precision.
This commit should allow graceful fallback if servers with
XInput 2.3 aren't supported.
https://bugzilla.gnome.org/show_bug.cgi?id=677215
Currently, we have a few function wrappers in the shell for pointer
barriers. If we want to implement interactive features on barriers,
we need some sort of signal to be notified of the interactivity.
In that case, we need to make a more sophisticated object-based wrapper
for a pointer barrier. Add one, and stick it in mutter.

Some windows may already have event masks on them that we've selected
for, especially if we're using GTK+ windows. In particular, this fixes
window menus in the XI2 port.
https://bugzilla.gnome.org/show_bug.cgi?id=690581
gdk_device_manager_get_client_pointer which in calls
XIGetClientPointer seems to be very slow in a XI2 world.
So use
gdk_x11_device_manager_lookup (gmanager, META_VIRTUAL_CORE_POINTER_ID)
instead.

This new hint allows compositors to know what portions of a window
will be obscured, as a region above them is opaque. For an RGB window,
possible to glean this information from the bounding shape region of
a client window, but not for an ARGB32 window. This new hint allows
clients that use ARGB32 windows to say which part of the window is
opaque, allowing this sort of optimization.

With the shape region always set, it turns out the bounding region
is only used in one place, that's easily replaced with a variable
we already have available to us.
https://bugzilla.gnome.org/show_bug.cgi?id=679901
With recent changes in the way the window mask texture is constructed,
the shape_region is always set, which means that we can remove
conditionals checking if the shape region is set.

Currently we only unredirect monitor sized override redirect windows.
This was supposed to catch fullscreen opengl games and improve
their performance.
Newer games like fullscreen webgl games and SDL2 using games (like L4D) as well as wine based games do not use override redirect windows so we need a better
heuristic to catch them.
GLX windows always damage the whole window when calling glxSwapBuffers and
never damage sub regions. So we can use that to detect them.
The new heuristic unredirects windows fullscreen windows that have damaged the
whole window more then 100 times in a row.

We should call meta_window_actor_detach not
meta_window_actor_queue_create_pixmap to create a new pixmap when we redirect a
previously unredirected window again.

We want to put barrier wrappers in mutter, which requre XFixes 5.0.
XFixes 5.0 was released in March, 2011, which should be old enough
to mandate support for.
