The code that has been deprecated should live into its own directory,
both in the repository and when installed. This should make it clear
which functionality is actually maintained and which is not.
We start with an oldie: the frame source API.
On top of the existing "Settings" group in the settings.ini file we
should have two more groups:
Environment - contains all the configuration possible through
environment variables
Debug - contains all the possible debug variables
ClutterSettings should be able to load its initial state by using
configuration files in SYSCONFDIR and XDG_CONFIG_HOME. This allows
Clutter to have a system (and user) configuration on platforms that
do not have XSETTINGS bridges.
We already have two mechanisms for controlling the font rendering
quality on a per-application basis:
• ClutterSettings properties
• clutter_backend_set_font_options()
The font flags were always a stop-gap solution, and one that tried to
simplify a fairly complex issue beyond the point of actually being
useful.

The grab API is a relic of Clutter 0.6, and hasn't been through proper
vetting in a *long* time — mostly due to the fact that we don't really
like grabs, and point to the ::captured-event as a way to implement
"soft grabs" in toolkits and applications.
The implementation of full and device grabs uses weak references on
actors instead of using the ::destroy signal, which is meant exactly for
the case of releasing pointers to actors when they are disposed.
The API naming scheme is also fairly broken, especially for
device-related grabs.
Finally, keyboard device grabs are just not implemented.
We can, in one go, clean up this mess and deprecate a bunch of badly
named API by introducing generic device grab/ungrab methods on
ClutterInputDevice, and re-implement the current API on top of them.
GLib deprecated g_thread_init(), and threading support is initialized
by GObject, so Clutter already runs with threading support enabled. We
can drop the clutter_threads_init() call requirement, and initialize the
Big Clutter Lock™ on clutter_init(). This reduces the things that have
to be done when dealing with threads with Clutter, and the things that
can possibly go wrong.
The Big Clutter Lock™ can now be a static GMutex, since GLib supports
them. We can also drop a bunch of checks given the recent changes in
GLib threading API.
The static initializer for GMutex has been removed from GLib.
The g_thread_supported() call can also be removed: threading is always
enabled in GLib ≥ 2.31.
This commit introduces a unicode-to-keyval conversion function that
performs identical action as the gdk version of that function. Also
added is the necessary table holding all the conversion values.

If we do project() → get_bounding_box(), we'll try to complete the
volume twice, which whacks out all the lazily computed vertices.

This adds a simple conformance test which sets up a few shader effects
using both the old style with clutter_shader_effect_set_source and the
new style by overriding get_static_shader_source. The effects are then
verified to confirm that they drew the right pixel colour.

This is used as an alternative to calling
clutter_shader_effect_set_shader_source. A ClutterShaderEffect
subclass is now expected to implement this method to return the source
for the effect that will be used for all instances of this
subclass. It is only called once regardless of the number of instances
created. That way Clutter can avoid recompiling the shader source for
every new instance of the effect.

The asynchronous loading code could do with some modernization.
First of all, we should drop the internal GMutex held when manipulating
the boolean flags: it's far too expensive for its role, and modern GLib
provides us with bitlocks that are quite a lot faster.
Then we should consolidate most of the implementation into something
smaller and more manageable.
