Bug 1014 - Clutter Animation API Improvements * clutter/Makefile.am: * clutter/clutter.h: Update the build * clutter/clutter-types.h: Add AnimationMode, an enumeration for easing functions. * clutter/clutter-alpha.[ch]: Add the :mode property to control the function bound to an Alpha instance using an enumeration value. Also add six new alpha functions: - ease-in, ease-out, ease-in-out - sine-in, sine-out, sine-in-out * clutter/clutter-deprecated.h: Deprecate the #defines for the alpha functions. They will be replaced by entries in the ClutterAnimationMode. * clutter/clutter-interval.[ch]: Add ClutterInterval, an object for defining, validating and computing an interval between two values. * clutter/clutter-animation.[ch]: Add ClutterAnimation, an object responsible for animation the properties of a single actor along an interval of values. ClutterAnimation memory management is automatic. A simple wrapper method for ClutterActor is provided: clutter_actor_animate() which will create, or update, an animation for the passed actor. * clutter/clutter-debug.h: * clutter/clutter-main.c: Add a new 'animation' debug note. * clutter/clutter-script.c: Clean up the alpha functions whitelist, and add the new functions. * doc/reference/clutter/Makefile.am: * doc/reference/clutter/clutter-sections.txt: Update the API reference. * doc/reference/clutter/clutter-animation.xml: Renamed to doc/reference/clutter/clutter-animation-tutorial.xml to avoid clashes with the ClutterAnimation section. * doc/reference/clutter/clutter-docs.sgml: Renamed to doc/reference/clutter/clutter-docs.xml, as it was an XML file and not a SGML file. * tests/Makefile.am: * tests/interactive/Makefile.am: * tests/interactive/test-animation.c: * tests/interactive/test-easing.c: Add two tests for the new simple animation API and the easing functions. * tests/interactive/test-actors.c: * tests/interactive/test-behave.c: * tests/interactive/test-depth.c: * tests/interactive/test-effects.c: * tests/interactive/test-layout.c: * tests/interactive/test-multistage.c: * tests/interactive/test-paint-wrapper.c: * tests/interactive/test-rotate.c: * tests/interactive/test-scale.c: * tests/interactive/test-texture-quality.c: * tests/interactive/test-threads.c: * tests/interactive/test-viewport.c: Update interactive tests to the deprecations and new alpha API.
