Dispose() may be called more than once, so calling g_free directly
on the device name is unsafe. Instead, use g_clear_pointer() to
make sure we don't attempt to free the memory again.

When support for implicit animation of actor position was added,
the optimization for not queueing when allocating an actor back
to the same location was lost. This optimization is important
since when we are hierarchically allocating down from the top of
the stage we constantly reallocate the actors at the top of the
hierarchy back to the same place.

When the source actor potentially changes size, that shouldn't
necessarily result in the target actor being redrawn - it should
be like when a child of a container is reallocated due to changes
in its siblings or parent - it should redraw only to the extent
that it is moved and resized. Privately export an internal function
from clutter-actor.c to allow getting this right.

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• most of the layout API is legacy, and has been replaced by the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• the animation API is legacy, and has been replaced by the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.
