Avoid double argument checking, and a deprecation warning when
implementing create() as a wrapper around create_region(), by using
a simple internal function.
The number of deprecations in clutter-main.h makes the header harder to
parse, and more confusing. We can use a separate header under the
deprecated subdirectory to hold all the deprecated symbols.
Since Xlib.h is such a terrible citizen when it comes to symbol
namespacing it's not desirable to include Xlib.h if it is not absolutely
required. Cogl now has a standalone cogl-xlib.h that should be included
whenever any xlib specific symbols are required.
This patch updates clutter to include <cogl/cogl-xlib.h> wherever
clutter needs to use xlib specific cogl apis.

We use an atexit() handler to print out the profile report coming from
Uprof. The g_atexit() call has been deprecated by GLib, but since this
use case is pretty specific and it's not meant to be turned on by
default (or distributed) then we can safely disable the deprecation
warnings inside clutter-profile.c.
The g_atexit() function has been deprecated in GLib as it is a fairly
bad idea in basically all cases.
We could probably use a GCC destructor if we didn't care about
portability, but for the time being we just remove the atexit() handler
that disposed the backend.
There are a couple of gotchas in the 'mapped' flag that are not properly
documented, or are documented only in the actor_invariants.txt file; we
should have a proper description in the API reference as well, to avoid
confusion.
Since the Windows GUI system is assuming multithreadedness, initializing
locks after entering the GUI portion on Windows is likely to cause
problems[1][2], which results many Clutter programs to crash due to
releasing resources that they did not own.

Or, better, the fact that the behaviour of any Clutter function will be
undefined in case the initialization fails.
The value returned by clutter_init() and friends has to be handled
properly.
Since the image backend is something now dealt with by Cogl there is no
need to check the experimental status of the backend in the Clutter
configure script.

This removes the create_texture implementation for ClutterBlurEffect
because we already account for padding in the get_paint_volume
implementation so we were creating textures larger than necessary.

GLX is now totally abstracted by Cogl so the "glx" flavour is actually
only used to determine the soname of clutter now so we don't actually
have to check for the glx header or that libGL provides any GLX symbols.

Instead of directly using the GLSL names for the builtins in the
shaders for test-shader and test-pick, this makes it use the Cogl
wrapper names instead. That way it will be portable to GLES2 as well.

Just like ClutterBindConstraint has two shorthand enumerations for binding
position and size and avoid using multiple instances, ClutterAlignConstraint
should have a way to align an actor with the same alignment factor on both
axis at the same time; this is especially useful for centering actors.
The CLUTTER_DEBUG class of debugging flags is meant for debugging notes,
while the CLUTTER_PAINT debugging flags are for changing the output of
the paint cycle. Painting the DeformEffect tiles should go in the latter.
This function is called when the backend is being disposed - as a way
of releasing all ClutterShader. This doesn't take into account three
things:
- ClutterShader is deprecated
- the Backend is *never* disposed
- once the process terminates, all its resources are automatically
released by the OS
So the _clutter_shader_release_all() function is a pointless exercise
in futility.
Just like we turn everything on with --disable-deprecated, we have to
turn everything off with --enable-deprecated. This means disabling the
deprecation warnings from the compiler as well.
Just like GLIB_DEPRECATED and GLIB_DEPRECATED_FOR, Clutter should have
its own wrappers for G_DEPRECATED and G_DEPRECATED_FOR, to allow opting
out of deprecation warnings.
Deprecation warnings are enabled by default, now, even when building
Clutter.
