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.
We still use ClutterGeometry internally in a couple of places, but we
should really move away from that flawed rectangle data type, and use
the Cairo one.
Sadly, we still have some public API that we cannot remove yet.
Setting the default frame rate does not do anything even remotely
useful, unless synchronization to the vertical refresh rate is also
disabled - which can only be done through environment variable or
through configuration file. Having a programmatic way to change the
default frame rate is, thus, completely pointless.
Changing the default frame rate through environment variable and
configuration file is still allowed.
In response to the following moved to deprecated in the following commits:

main: Move deprecated symbols to a separate header
40d703a0
backend: Move deprecated symbols to a separate header
b19c9196
actor: Move deprecated symbols into separate headers

Move clutter-keysyms-compat.h to the deprecated section

Don't use a -deprecated suffix for headers
11420a70
group: Move deprecated macro into its own header
98b467f9
stage: Move the deprecated macros to a separate header
A GDK backend for clutter was added in commits 610a9c17
(Add A new GDK backend) and f14cbf5b (gdk: Allow disabling event retrieval)
These are not included in the Win32 builds for the moment as GDK3 is
quite unstable on Windows at this time
-Update clutter-version.h.win32.in to reflect the state of
clutter-version.h.in commit 21a24c86 (updated in commit 8249e488)
-Also add clutter_check_windowing_backend to clutter.symbols as a result.
The clutter-stage.h header still has a bunch of macros that have, for
reasons unknown[*], survived the 1.0 API cut and have long since been
deprecated. Let's hide them under the deprecated/ carpet and let us
never speak of them ever again.
[*] pretty sure alcohol or other psychotropic substances were involved
but I take the 5th on that.
