sanspie 515f4ca1b3 Stage 11a: animation (D333–D340, D344, D354–D357)
Clips (.aeanim) and controllers (.aectrl) with importers, AnimationPlayer and Animator with crossfades, root motion and events on fixed steps, rewind support. Editor: Animation panel (dope sheet, curves, record, preview, trajectory), Animator panel, sprite sheet slicer and flipbooks, Programming workspace, export panel redesign. Motion 2D ledge climb. 11c: the component and Create palette.
