35c6179a8e animator: avoid walking off empty list
When removing the last key in a list, the last part of the for statement
could cause dereferencing (NULL)->next and thus segfaulting.

452cb1abbf animator: fix looping when doing cubic interpolation
When using interpolation and the last key is not at 1.0 a bouncing
artifact could be observed after the keys.

8afb091f56 animator: retain ease-in/interpolation when changing first key
Duplicate the existing ease-in/interpolation mode for the property when
removing, replacing the first key for a property or adding a new first
key for a property.

d45395d78b animator: fix crash when setting keys on running animator
When inserting or modifying keys of a running animator the internal
iterators per property could go out of sync. Reinitializing the
iterators if the timeline is running avoids this.

09d8460a5c animator: s/clutter_animator_run/clutter_animator_start/
This is consistent with choice of words in clutter_timeline_start and
makes the API less surprising.

9a55ddc7c3 animator: restore accidentally removed break
In 505e5966 a break statement was removed by accident, causing the
animator to enter infinite loops if no initial key is present.

505e5966e4 Do not overwrite the initial key, making ease-in work as expected.
Fixes bug #2008, where a property with ease-in would jump instead of
start at the properties initial value.

Also, fix the introspection annotations.

655cb966c0 docs: Add visual cue for Animator's key frames
We should explain what a "key frame" is for ClutterAnimator, possibly
with some sort of visual cue.

This allows me to demonstrate my poor skills at using Inkscape, as well
as my overall bad taste for graphics design.

c291d5a660 animator: Add a :timeline property
It would be useful to be able to share the Timeline across different
animator instances, or with different animation constructs. Also this
allows sharing definitions of Timelines in ClutterScript.

6415825339 animator: Remove NULL check in remove_key()
The arguments for remove_key() can be NULL, but there is an extraneous
assertion that fails if they are. The pre-conditions should match the
documentation, in this case.

in copy and paste.

26e22b2ede Conditionally use G_VALUE_COLLECT_INIT() macro
GLib 2.24 (but starting from the 2.23.2 unstable release) added a new
macro for collecting GValues from a va_list.

The newly added G_VALUE_COLLECT_INIT() macro should be used in place
of initializing the GValue and calling G_VALUE_COLLECT(), and improves
the collection performances by avoiding multiple checks, free and
initialization calls.

ClutterAnimator from script, otherwise only the last used property will
be used

667222c301 analysis: ClutterAnimator/1
Do not de-reference a void*; use a temporary variable -- after
checking the contents of the pointer. This actually simplifies
the readability and avoids pulling a Lisp with the parentheses.

4dd11d6915 animator: Provide a ClutterScript parser
The whole point of having the Animator class is that the developer can
describe a complex animation using ClutterScript. Hence, ClutterAnimator
should hook into the Script machinery and parse a specific description
format for its keys.

790a13c0d9 animator: Allow retrieving type property type from a key
When asking a key for its target value we also ask the developer to pass
in an initialized GValue - but we don't make it easy to know the type of
the GValue. A developer has to ask the GObject class for the GParamSpec
and then initialize the GValue, instead.

Since we know the type of the GValue we should provide a getter for it.

We should also allow developers to throw at us GValue with compatible and
transformable types.

Finally, all the accessors should be constified.

4cc269a468 Add ClutterAnimator
ClutterAnimator is a class for managing the animation of multiple
properties of multiple actors over time with keyframing of values.

The Animator class is meant to be used to effectively describe
animations using the ClutterScript definition format, and to construct
complex implicit animations from the ground up.
