Constructor
WorkspaceDragger
new WorkspaceDragger(workspace)
Class for a workspace dragger. It moves the workspace around when it is being dragged by a mouse or touch. Note that the workspace itself manages whether or not it has a drag surface and how to do translations based on that. This simply passes the right commands based on events.
