Clean up Workspace animation. #567865

Browse Source 
Use Tweener.registerSpecialPropertyModifier to handle moving windows in
straight lines on the screen even while their parent workspaces are also
moving.

Have the remove buttons track their parent workspace scale and deal with
it automatically rather than having special cases in each Workspace method.
