When animating an actor through clutter_actor_animate() and friends we
might want forcibly detach the animation instance from the actor in
order to start a new one - for instance, in response to user
interaction.
Currently, there is no way to do that except in a very convoluted way,
by emitting the ::completed signal and adding a special case in the
signal handlers; this is due to the fact that clutter_actor_animate()
adds more logic than the one added by clutter_animation_set_object(),
so calling set_object(NULL) or unreferencing the animation instance
itself won't be enough.
The right way to approach this is to add a new method to Clutter.Actor
that detaches any eventual Animation currently referencing it.

If we're depending on an uninstalled .gir, use --include-uninstalled.
We need to explicitly specify Cogl to let the scanner know it's also
uninstalled.

Flushing the framebuffer state can cause some drawing to occur if the
framebuffer has a clip stack which needs the stencil buffer. This was
causing the array pointers set up by enable_state_for_drawing_buffer
to get mangled so it would crash when it hits glDrawArrays. This patch
moves the framebuffer state flush to before it sets up the array
pointers.

This requires some autotools magic when setting up the environment
through autogen.sh, because autoreconf does not do the right thing
by default.
The correct order for setting up localization is:
‣ autopoint
‣ aclocal
‣ ...
otherwise aclocal will copy the system's gettext.m4 instead of honouring
the version we specified with AM_GNU_GETTEXT_VERSION in configure.ac.
I think this is what commit 2cf1405506 intended to do since it
specifically mentioned cleaning up the trap in
clutter_x11_texture_pixmap_set_pixmap, but although it moved the untrap
to only be done in the case where Pixmap != None it left the position of
the trap itself unchanged. This meant the error trapping wouldn't be
balanced if pixmap == None since the untrap wouldn't be done. We now
only trap and untrap around the XGetGeometry call done when pixmap !=
None.

With currently distributed versions of Mesa, calling XFreePixmap()
before glxDestroyPixmap() will cause an X error from DRI. So, we
need to make sure that we get rid of the CoglTexturePixmapX11 before
we XFreePixmap().
clutter_x11_texture_pixmap_dispose(): Call
clutter_x11_texture_pixmap_set_pixmap() instead of using XFreePixmap
directly so that we leverage the text-clearing hack and destroy
things in the right order.
clutter_x11_texture_pixmap_set_pixmap(): Don't do a pointless roundtrip
and trap a pointless error when setting pixmap to None.
clutter_x11_texture_pixmap_set_pixmap(): Free damage resources when
we are setting Pixmap to None.
clutter_x11_texture_pixmap_set_window(): When setting a new window
or setting the window to None, immedediately call
cluter_x11_texture_pixmap_set_pixmap(). This means that set_window(None)
immediately will free any referenced resources related to the window.

Comprehensively add (out) annotations to functions parameters
returning int/float/double.
Not handled here: structure out returns like ClutterColor or
ClutterPerspective or GValue that should get (out caller-allocates).

Since we're not using intltool, and since we need to let people on
Transifex generate their translations, we need to add the POT file
to the repository.
We are finally able to add the properties nicks and blurbs to the list
of translatable strings, for UI builders to use. This means bumping the
list of strings from 20-ish to a whopping 400. Whoopsie.
Remove the fix-ups for shave and gtk-doc with libtool 1.5: we don't use
shave any more, and we require libtool 2.2.
Also remove the unnecessary autopoint: we use autoreconf, which calls it
automatically.
(element-type) should have a full name like Clutter.Actor rather than
a non-namespaced name like Actor. gobject-introspection has become
more strict about this with the recent scanner rewrite.

• Use addprefix instead of manually concatenating $(srcdir)
• Use AM_V_GEN instead of QUIET_GEN, to avoid inter-dependencies
• Do basic checks on GLIB_MKENUMS and GLIB_GENMARSHAL being defined
• Do checks on the required variables being defined
What happens now if you rename an enum inside a header:
• glib-mkenums generates the header file
• a comparison is made with the previous version of the heade is made
and no difference is found as you don't remove or create enums
• the compilation of the generated mkenums c file fails because it has
not been regenerated with the new, renamed, enum.
That's why the generated clutter-enum-types.c needs to depend on the
headers too.
Of course such scenario should not happen in stable releases as enums
are part of the API, but renaming enums happens in the development cycle
and create compilation errors (very annoying when doing git bissects for
instance).
*** This is an API change ***
Replaced the original drag-threshold property with two separate
horizontal (x-drag-threshold) and vertical (y-drag-threshold)
thresholds.
It is some times necessary to have different drag thresholds for the
horizontal and vertical axes. For example, when a draggable actor is
inside a horizontal scrolling area, only vertical movement must begin
dragging. That can be achieved by setting the x-drag-threshold to
G_MAXUINT while y-drag-threshold is something usual, say, 20 pixels.
This is different than drag axis, because after the threshold
has been cleared by the pointer, the draggable actor can be dragged
along both axes (if allowed by the drag-axis property).

Creating new materials for every Texture instance results in a lot of
ARBfp programs being generated/compiled. Since most textures will just
be similar we should create a template material for all of them, and
then copy it in every instance. Cogl will try to optimize the generation
of the program and, hopefully, will reuse the same program most of the
time.
With this change, a simple test shows that loading 48 textures will
result in just two programs being compiled - with and without batching
enabled.

When disposing a material layer of type 'texture' we should check that
the texture handle is still valid before calling cogl_handle_unref().
This avoids an assertion failure when disposing a ClutterTexture.
Uses ClutterAnimator to implement a reasonably complex
animation of a single actor (movement along a path with
simultaneous scaling).
Provides a metaphor for thinking about ClutterAnimator
animations (stage directions) and explains keys and key
frames in some depth. Also compares ClutterAnimator
with other possible approaches to this type of animation
(implicit animations, ClutterState).
Added another JSON example to show how transitions can
be easily overlapped when using ClutterAnimator (two
sequences of 5 transitions, simultaneous with two
sequences of 1 transition).
Modified the C JSON loader program so it can be used with
this example as well.
