Instead of defining CLUTTER_ENABLE_EXPERIMENTAL_API and
COGL_ENABLE_EXPERIMENTAL_API in individual source files, enable
them on the command line. We weren't tracking exactly what pieces of
experimental API we were using and we were using the experimental
API in most source files that used Clutter and Cogl, so the
local #defines were annoying rather than useful.

It's possible that a client might update the (extended)
_NET_WM_SYNC_REQUEST_COUNTER counter twice without actually drawing
anything. In that case, we still should send a _NET_WM_FRAME_DRAWN
message since it's hard for a client to know every case in which
no damage is generated. For now, do it the easy way by forcing a
stage repaint.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Resizing the frame triggers creation of a new backing pixmap for the
window, so we should do that first before we resize the client window
and mess up the contents of the old backing pixmap.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
When the application provides the extended second counter for
_NET_WM_SYNC_REQUEST, send a client message with completion
information after the next redraw after each counter update
by the application.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
If an application provides two values in _NET_WM_SYNC_REQUEST_COUNTER,
use that as a signal that the applications wants an extended behavior
where it can update the counter as well as the window manager. If the
application updates the counter to an odd value, updates of the
window are frozen until the counter is updated again to an even value.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=677215
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.
https://bugzilla.gnome.org/show_bug.cgi?id=679901
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.
https://bugzilla.gnome.org/show_bug.cgi?id=683786
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.

Using a public method for setting the (cached) icon geometry rather
than accessing the struct members directly allows setting the icon
geometry from extensions.

We have some code in gnome-shell that does the equivalent of:
window.get_workspace() == workspace || window.is_on_all_workspaces();
which is a bit unwieldy. We already have a method in mutter,
so use that and document it.
https://bugzilla.gnome.org/show_bug.cgi?id=691744
With some recent changes to how mask textures are constructed from
shapes, a helper method we made was only called in one place, allowing
us to drop a reference/destroy, and remove a double clear.

Due to a conditional error, meta_region_builder_add_rectangle was called
on every single blank pixel, rather than at the end of spans. With the new
rename, it's fairly clear to see the error. Fix the check to ensure that
we no longer make extraneous calls to meta_region_builder_add_rectangle.

GtkWindow added the BACKGROUND style class to all windows, which the
CSS file selects on to set a background color for all windows. Without
this, the background color becomes undefined, and thus window frames
look like they have "glitchy" graphics.

The minimize action does not make much sense without a window list,
which is why its default keybinding was removed in bug 643609;
getting the focused window out of the way quickly can still be useful
though, so change the description to "Hide window" instead, which does
not imply a window list. We will then assign a default shortcut again.
https://bugzilla.gnome.org/show_bug.cgi?id=682887
MetaButtonLayout is extremely unfriendly for introspection: its fields
are arrays of a fixed length, but the actual length is determined by
a custom stop value (e.g. not NULL / 0).
Without API changes this will never work nicely in introspection, but
we can at least make it work; start by filling up unused fields with
the stop value rather than leaving it at random values.
https://bugzilla.gnome.org/show_bug.cgi?id=689263
The style context of the widget is rarely what we want. We won't
fix this to be a MetaFrames style context yet; this just changes
the internal API.

Currently, we ping windows only when attempting to delete them, but
if the application is not responding, we want to show the dialog
as soon as possible. Given that we cannot be passively notified that
the window stopped responding with the current X11 protocol, a good
workaround is to ping the window when activating it.
If the window stops responding while active, it is expected the user
will try to switch window or open the overview, and when coming back
he'll get the failure dialog.
https://bugzilla.gnome.org/show_bug.cgi?id=684340
Add meta_window_check_alive(), which is a simple wrapper over
meta_display_ping_window(), and takes care of showing the "Application
is not responding dialog" if needed.

We want to maintain the invariant that an attached modal dialog is always
of type MODAL_DIALOG, so recompute is_attached_dialog() when the window

This removes our final dependency on Core Events, meaning
we can remove support code for them soon.
This commit is a bit ugly as it requires ui having a dependency on
core, but this is already a hack, so this is thus a hack inside a
hack, and two hacks make a right or however that goes.

In random places that are not grabs, we selected for events on
things like the root window, stage window, COW and more. Switch
these over to using the proper XI2 APIs.

It's unlikely that we'll ever want to support multiple pointer
