-Make the contents of config.h.win32.in more like config.h.in
-Define CLUTTER_INPUT_WIN32 accordingly (no GDK3 defines yet, until
GDK3 on Windows is more stable)
Instead of implementing create_stage() and a constructor for
ClutterStageOSX, we can use the default implementations in
ClutterBackend, and spare us some code duplication.
Create the device manager during the event initialization, where it
makes sense.
This allows us to get rid of the per-backend get_device_manager()
virtual function, and just store the DeviceManager pointer into the
ClutterBackend structure.
All StageWindow implementation already have back pointers, but we need a
unified API to actually set them from the generic code path; we can use
properties on the StageWindow interface — though this requires fixing
all backends at the same time, to avoid GObject complaining.
Instead of piggybacking on the EGL backend, let's create a small
ClutterBackend for the CEx100 platforms. This allows us to handle the
CEx100-specific details in a much cleaner way.
All the functionality that ClutterBackendCogl provided has been moved
into ClutterBackend itself, so there is no need to have this class
around in the source.
Cogl-based backends can derive directly from ClutterBackend.
Don't replace create_context(): given that the X11 backend already uses
Cogl for the context creation, we can just provide the right data
structures ourselves.
Since we use Cogl for the context creation we can now provide a default
context creation that should just work, plus a couple of hooks to allow
plugging into the creation sequence for platforms supported by Cogl that
require special handling — like foreign displays or alpha-enabled swap
chains.
The various backends have now two choices: either replace the
create_context() in its entirety, or plug themselves into the default
context creation.
Input backends are, in some cases, independent from the windowing system
backends; we can initialize input handling using a model similar to what
we use for windowing backends, including an environment variable and
compile-/run-time checks.
This model allows us to remove the backend-specific init_events(), and
use a generic implementation directly inside the base ClutterBackend
class, thus further reducing the backend-specific code that every
platform has to implement.
This requires some minor surgery to every single backend, to make sure
that the function exposed to initialize the event loop is similar and
performs roughly the same operations.
Right now, we pass through to Pango unrecognized hexadecimal formats
when parsing colors from strings. Since we parse all possible formats
ourselves, we can do validation ourselves as well, and avoid the Pango
path.
Previously, if there was whitespace between "l" and the comma before the
alpha value, parsing would fail. This patch allows that whitespace
making it consistent with whitespace being allowed everywhere else.

These methods are short-hands for accessing the position and size,
which are already shorthands for accessing the various dimensional
and positional attributes. Plus, they use ClutterGeometry, which is a
fairly bad data type for a rectangle.
