This adds a COGL_DEBUG=wireframe option to visualize the underlying
geometry of the primitives being drawn via Cogl. This works for triangle
list, triangle fan, triangle strip and quad (internal only) primitives.
It also works for indexed vertex arrays.
In cogl_vertex_buffer_indices_get_for_quads() we sometimes have to
extend the length of an existing array, but when we came to unref the
previous array we didn't first check that it wasn't simply NULL.
This adds an optional data argument for cogl_vertex_array_new() since it
seems that mostly every case where we use this API we follow up with a
cogl_buffer_set_data() matching the size of the new array. This
simplifies all those cases and whenever we want to delay uploading of
data then NULL can simply be passed.
The Behaviour class and its implementations have been replaced by the
new animation framework API and by the constraints for layout-related
animations.
Currently, we need to make tests build, so we undef DISABLE_DEPRECATED
in specific test cases while they get ported.
The paint volume structure is cached in the Actor it references, and
this causes a reference cycle.
The paint volume is going to be used when painting, so the actor must
still be valid - otherwise Clutter will bail out far before than
accessing the actor pointer in ClutterPaintVolume.
Otherwise, we could have used dispose() to check for a valid actor and
remove a reference if the actor field is !NULL; it feels less clean,
though, since we're effectively managing an extra reference on
ourselves.

Building the API reference for Cogl 2.0 is fairly confusing: the API
itself is experimental and for internal use only -- though we want
feedback for it.
Let's build the API reference only when Clutter is configured with a
specific configure switch, so that people that wish to give feedback on
the API and its documentation can do it.
Starting from the 2.27 cycle, GLib is exposing a monotonic clock with
microseconds granularity throughout the time-based API. We can start
using it, given that the old, non-monotonic version is going to be
deprecated by the same cycle.
GLib 2.28 will deprecate GTimeVal and related API in favour of
standardizing on microseconds granularity for all time-based API.
Clutter should switch too.
All of the current users of GTimeVal convert to milliseconds when
doing time operations, and use GTimeVal only as storage. This can
effectively be replaced by a gint64.
The Master Clock uses a microsecond resolution, except when interacting
with the main loop itself, since the main loop has a millisecond
resolution - at least until Ryan Lortie manages to switch that too to
microseconds on Linux.
The clutter_timeline_do_tick() function was erroneously not privatized,
but it was still assumed to be private; we should just remove it from
the public symbols.
For internal usage, writing:
clutter_actor_get_name (actor) != NULL
? clutter_actor_get_name (actor)
: G_OBJECT_TYPE_NAME (actor)
is overly verbose and does two type checks. A simple, internal method
for getting the same result without type checks would be much more
appreciated.

cookbook: Looping animation examples
Added a recipe giving examples of how to loop
animations for each part of the animation API (implicit,
animator, state).
The discussion covers looping a fixed number of times
and inverting a single implicit animation to create
a loop which goes back to its start on each iteration.
The "watch" function functionality in xsettings-client.c is designed
for setups like GDK where filters are per-window. If we are going
to pass all events to _clutter_xsettings_client_process_event()
anyways, we can just pass in NULL for watch.
This avoids a nasty infinite loop where an event would get processed
triggering removing a filter and adding a new filter, which would
immediately run and remove a filter and add another and so on
ad-infinitum.

The same behavior can be achieved by capturing events on stage while
button is pressed. This fixes a problem when using click and drag
actions on the same actor as there no grabs involved.

There's no longer any need to use the GL handle in the callback for
_cogl_texture_foreach_sub_texture_in_region because it can now work in
terms of primitive cogl textures so it has now been removed. This
would be helpful if we ever want to make the foreach function public
so that apps could implement their own primitives using sliced
textures.
