Since the journal is flushed on context switches, trying to use a cached
buffer means that we will use glReadPixels when picking, which isn't what
we want. Instead, always use a clipped draw, and remove the logic for
caching the pick buffer.

The table layout manager has various issues:
• no support for RTL flipping
• most of the layout API is legacy, and has been replaced by the
alignment and expansion flags on ClutterActor
• the animation API is legacy, and has been replaced by the
implicitly animatable allocation
• the spanning cells handling is a bit awkward, as is its API
On top of that, we imported the grid layout management policy from GTK+
into ClutterGridLayout, which provides all the required features in a
more well-designed API.
Instead of wasting time and resources updating TableLayout, we should
deprecate it and point developers of the GridLayout.
This adds clutter_event_add/remove_filter which adds a callback
function which will receive all Clutter events just before the event
signal is emitted for them. The event filter will be invoked
regardless of any grabs or captures. This will be used by Mutter which
wants to access the events at a lower level then the event bubbling
mechanism. It needs to see all mouse motion events even if there is a
grab in place.

The state that the X server sends for button events, by specification,
contains the button state before the event. We need to synthesize in
the result of the event in order to determine what the current button
state is.

XFixesShowCursor / XFixesHideCursor does not actually take the suppled
window argument into account -- the effect is actually global. Use
XDefineCursor instead.

Destroying an actor is supposed to destroy all of its children, so
it makes sense to reason that destroying the stage should destroy all
of its children, too.
Unfortunately, it seems that the stage removed all of its children
without destroying them before chaining up to what would destroy all
of its children, for whatever reason. Change this to a destroy so
resources get cleaned up.
The TextureNode premultiplies the blend color passed to the node
constructor, so we need to document the fact properly to avoid
causing premultiplication twice.
We can also allow passing NULL for a color, and use a fully opaque
white, to make the code slightly more friendly.
ClutterTextureNode will do that for us when converting the ClutterColor
to a CoglColor, so we can simply pass a white color with the correct
alpha channel.
The calculation (n - 1) * spacing to compute the total spacing is
only correct for n >= 1 - if there are no visible rows/cols, the
required spacing is 0 rather than negative.

For some XI2 we do not have a Stage associated to the event window.

On high DPI density displays we create surfaces with a size scaled up by
a certain factor. Even if the contents stay at the same relative size
and position, we need to compensate the scaling both when changing the
surface size, and when dealing with input.
https://bugzilla.gnome.org/show_bug.cgi?id=705915
In order to transparently support high DPI density displays, we must
maintain all coordinates and sizes exactly as they are now — but draw
them on a surface that is scaled up by a certain factor. In order to
do that we have to change the viewport and initial transformation
matrix so that they are scaled up by the same factor.

The added support is very very basic (single touch, motion only,
no acceleration, no pressure recognition), but anything more
complex requires a state machine that will be hopefully provided
by libinputcommon in the future.
And at least, with this patch the pointer moves, which will be
useful for people testing wayland in 3.10 without a physical mouse.

In situations when the default backend would fail (for example
when compiled with X11 support but run without DISPLAY), or
when the application is using backend specific code, it makes
sense to let the application choose the backend explicitly.

It was a bad idea to add it, because clutter events are batched,
so by the time the application processes one, the keyboard state
internally tracked by clutter could be already different.
Instead, apps should use clutter_event_get_state_full()

We can't dispatch a motion event for EV_REL (because we don't
have yet the other half of the event), but we can't also queue
them at the end of processing (because we may lose some history
or have button/keys intermixed).
Instead, we use EV_SYN, which means "one logical event was
completed", and let the winsys-independent code do the actual
motion compression.

When we release a device, we lose all the events after that point,
so our state can become stale. Similarly, we need to sync the
state with the effectively pressed keys when we reclaim.
This ensures that modifier keys don't get stuck when switching
VTs using a keybinding.
https://bugzilla.gnome.org/show_bug.cgi?id=706494
When talking to other applications or serializing the modifier
state (and in particular when implementing a wayland compositor),
the effective modifier state alone is not sufficient, one needs
to know the base, latched and locked modifiers.
Previously one could do with backend specific functionality
such as clutter_device_manager_evdev_get_xkb_state(), but the
problem is that the internal data structures are updated as
soon as the events are fetched from the upstream source, but
the events are reported to the application some time later,
and thus the two can get out of sync.
This way, on the other hand, the information is cached in the
event, and provided to the application with the value that
was current when the event was generated.
https://bugzilla.gnome.org/show_bug.cgi?id=706494
These two devices are logically tied togheter, and their state
should always be the same. Also, we need to update them after
the event is queued, as the current modifier state (as opposed to the
modifier mask in the event) should include also the effect of the last
key press/release.
