When an actor carrying canvas content is repainted, it will currently reupload
the data from the buffer to a texture. While this is not a performance problem
on a desktop, some mobile environments take a big performance hit. This
change tracks data changes and only recreates the texture if necessary.

By creating and starting the timer on clutter_main() an assumption is made
that that is how the main loop will be run for all clutter applications.
With more and more applications moving to GApplication, this assumption no
longer holds true.
Moving to clutter_init() means we are starting the timer earlier than we
should, and by not stopping it when the main loop quits we are taking a
measure that is later than we should. I believe it is safe to consider
those are close enough to the actual beginning and quitting of the main
loop in practice.

The GetSystemMetrics() function returns wrong values for SM_CXSIZEFRAME,
SM_CYSIZEFRAME, SM_CXFIXEDFRAME and SM_CYFIXEDFRAME when built with Visual
Studio 2012 and 2013 (unless the XP compatibility setting for the
PlatformToolset entry is turned on), causing the window of Clutter programs
to automatically shrink to a point where they become unusable.
This patch uses AdjustWindowRectEx() for builds using Visual Studio 2012
and later, which deduces the required height and width of the Window
properly. Unfortunately we can't use this for the VS 2008/2010 builds as
they cause the Window to continually expand as the program is run.

Due to the way add_device() invariably adds to the master/slave device
lists, while keeping ClutterInputDevices 1:1 with device IDs, it may
leave invalid pointers in the list if add_device() is called multiple
times for the same device ID. There are two situations where this may
happen:
1) If devices are disabled and later enabled: devices are added invariably
to the master/slave lists on constructed(), but then on XIDeviceEnabled
they'd get added yet again.
2) Racy cases where the ClutterDeviceManager is created around the same time
XIHierarchyEvents are sent. When getting the XIDeviceInfo on constructed(),
these devices may already appear as enabled, even though XIDeviceEnabled
is seen through XIHierarchyEvents processed in the event loop sortly after.
This last case can be seen when starting gnome-shell on a different tty,
and entering in the one it's been spawned on, clutter initialization
happens around the same time devices are added back because of the tty
switch, and multiple extra ClutterInputDevices are created.

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.

-Combine entries in the property sheets and make it a bit more flexible,
and drop some redundant items
-Use Custom Build Rules for generating enumeration and marshalling sources,
and the .def file so that they can be wiped off when a "clean" is
requested, and regenerate automatically when the templates/.symbols
files are updated.
-Improve consistency by using ApiVersion rather than ClutterApiVersion
with the Visual Studio project for other components of the Clutter/GTK+
stack
-Get rid of unneeded configs in the "install" project
This is taken directly from the 1.16 series, as it seems that the 1.x
development starts from here, so put this here first and make the
neccessary adjustments as we go on.
This is necessary to avoid a deadlock with the compositor. When setting
a stage size before the stage was shown this would trigger a redraw
inside clutter_stage_wayland_resize. This redraw would result
in a call into eglSwapBuffers which would attach a buffer to the surface
and commit. Unfortunately this would happen before the role for the
surface was set. This would result in the compositor not relaying to the
client that the desired frame was shown.
With this change the call to wl_shell_surface_set_toplevel is always
made before the first redraw.
