MetaGestureTracker has been separating the "did I handle an event?" and the
"should the event be filtered out?" questions, merge this and make
handle_event() reply to "should the event be only handled by me?".
If a sequence wasn't accepted yet by the gesture tracker, the event will
go through (eg. not handled exclusively by the gesture tracker) and it'll
still be processed by Clutter, triggering gesture actions, and maybe
changing the sequence into other state.

The grabbing state is now checked for both pointer/touch devices
within the seat, and the grab start coordinates returned by
meta_wayland_seat_get_grab_info().
https://bugzilla.gnome.org/show_bug.cgi?id=733631
On X11 this works because only emulated pointer events are listened for. On
wayland, the single touch behavior must be enforced in touch events, ignoring
every other sequence.
https://bugzilla.gnome.org/show_bug.cgi?id=733631
This function tells the obvious on X11, and implements a similar mechanism
on wayland to determine the "pointer emulating" sequence, or one to stick
with when implementing single-touch behavior.
https://bugzilla.gnome.org/show_bug.cgi?id=733631
Due to the way the MetaGestureTracker processes every touch event, this
will tell as closely to Clutter as possible the current number of touches
happening on the stage.
Even though, this is subject to windowing behavior, on X11, rejected touches
will be soon followed by a XI_TouchEnd event, so the compositor will stop
seeing touch sequences that are still operating on clients. On wayland, touch
sequences are processed by the compositor during all their lifetime, so these
will stay on the MetaGestureTracker with META_SEQUENCE_PENDING_END state, yet
still tracked.
https://bugzilla.gnome.org/show_bug.cgi?id=733631
On wayland, touches are initially both handled by the compositor and sent
to clients, proceeding to cancellation on clients only after the compositor
claims the sequence for itself. Implement the cancellation detail through
MetaGestureTracker::state-changed.

The capability flags are determined from the device types of the slave devices
that are currently attached. This also happens whenever a device is added or
removed, so the capabilities are kept up to date, and clients know about these.
On VT switch, all slave devices are temporarily removed, so the cascade of
signals will make the seat end up with capabililities=0 while input is suspended.

Anytime the keymap is changed, either directly, or indirectly through the
keyboard capability being released/initialized, there should be a
notification of the modifiers being changed too.

xkb_state creation has been refactored out of clutter_evdev_set_keyboard_map(),
and used too in clutter_evdev_reclaim_devices(), so the xkb_state is fresh
clean after input is paused/resumed (and keyboard state possibly changed in
between)
https://bugzilla.gnome.org/show_bug.cgi?id=733562
Otherwise the focus_surface_listener list element becomes stale, and then
mangled if the devices' data is initialized again, and the memory memset().

If --stereo is passed, then the texture pixmap is created as a stereo
texture pixmap, and also, if passed in conjunction with --gears,
glxgears is also run with the -stereo option.

If --gears is passed on the command line, glxgears is run, and
is used for the source window rather than drawing solid rectangles
into a window we create outselves.

Add cogl_texture_pixmap_x11_new_left() and
cogl_texture_pixmap_x11_new_right() (which takes the left texture
as an argument) for texture pixmap rendering with stereo content.
The underlying GLXPixmap is created using a stereo visual and shared
between the left and right textures.

If we want to show quad-buffer stereo with Cogl, we need to pick an
appropriate fbconfig for creating the CoglOnscreen objects. Add
cogl_onscreen_template_set_stereo_enabled() to indicate whether
stereo support is needed.
Add cogl_framebuffer_get_stereo_mode() to see if a framebuffer was
created with stereo support.
Add cogl_framebuffer_get_stereo_mode() to pick whether to draw to
the left, right, or both buffers.
