[gnome-shell/wip/fmuellner/ease-actors: 12/20] dash: Directly tween actors



commit e09316bea36ab46cbd8a4bf77f5f5bc193c64fff
Author: Florian Müllner <fmuellner gnome org>

    dash: Directly tween actors
    
    Dash items are currently animated via the custom "childScale" and
    "childOpacity" properties. However since commit efb3025d8cdb, those
    properties actually control the scale-x/scale-y and opacity properties
    of the actor itself (not the child), so cut out the intermediate
    custom properties in favor of the "real" ones.
