Jasper St. Pierre e43fe98263 windowManager: Hold the window on the stage while going between workspaces
Right now the "move to workspace" keyboard shortcut transition isn't smooth. It
shows the window disappearing, hopping to the next workspace, and then sliding
into view. "Pin" the window to the stage while the animation is in progress,
then release it afterwards.
