2006-11-15 Emmanuele Bassi <ebassi@openedhand.com> * clutter/clutter-alpha.h: * clutter/clutter-alpha.c: Add a data parameter to the ClutterAlphaFunc; add a data+destroy parameter to clutter_alpha_set_func() and to clutter_alpha_new(), and turned the latter into clutter_alpha_new_full(); add a simple, empty constructor clutter_alpha_new(). These changes makes writing bindings a tad more easy, as bindings require passing their own functions in order to call the real alpha function. * clutter/clutter-behaviour.h: Clean up the header. * clutter/clutter-behaviours.[ch]: * clutter/clutter-behaviour-opacity.[ch]: * clutter/clutter-behaviour-path.[ch]: * clutter/clutter-behaviour-scale.[ch]: Split the ClutterBehaviourPath, ClutterBehaviourOpacity and ClutterBehaviourScale into their own files as they have been growing a bit. Fix ClutterBehaviourPath API. * clutter/clutter-media.h: Remove the commented "metadata_available" signal: gtk-doc chokes up on that. * clutter/clutter-timeline.h: * clutter/clutter-timeline.c: Remove the useless ClutterTimelineAlphaFunc signature; add missing accessor methods for the properties; clean up a bit. * clutter/clutter-util.h: * clutter/clutter-util.c: Remove unneeded function clutter_util_can_create_texture(). * clutter/clutter-feature.h: Sync the name of clutter_feature_get_all() with the name declared in clutter-feature.h. * clutter/Makefile.am: * clutter/clutter.h: Update. * examples/behave.c: Update to the new ClutterAlpha constructor. * examples/super-oh.c: Use the right pointer and avoid the compiler making a fuss about it.
