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.

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.

Cogl-1.16 has much deprecation that is done, which causes the build of
Clutter to generate lots of C4996 (deprecation) warnings. As in commit
fa8809d7 (Add COGL_DISABLE_DEPRECATION_WARNINGS to the build flags), do
likewise by adding this macro in the Visual C++ property sheets, so we
would have much less C4996 warnings during the build.
Please see bug 703877 for the rationale behind this.
