When we enter overview (overview appears, workspace disappears): - Workspace scales down from 1f to .8f with OvershootInterpolator(1.2f) at 200 ms - Workspace fades from 1f to 0 with OvershootInterpolator(1.2f) at 200 ms - Overview scales down from 1.33f to 1f with OvershootInterpolator(1.2f) at 200 ms - Overview fades from 0 to 1f with OvershootInterpolator(1.2f) at 200 ms When we exit overview (overview disappears, workspace appears): - Workspace scales up from .92f to .1f with DecelerateInterpolator() at 200 ms - Workspace fades from 0 to 1f with AccelerateInterpolator() at 200 ms - Overview scales up from 1f to 1.1f with AccelerateInterpolator() at 180ms - Overview fades from 1f to 0 with DecelerateInterpolator(1.7f) at 200 ms Parallax while the finger moves: Workspace translates half the distance as the shelf Bug: 79776746 Change-Id: I319d982cf202bcd6dbbcd68ffc5c0c7853629c7e
