 ####WGPendingViewAction
 Processes any pending view actions that the user has initiated with the mouse. This should be called once each time through your run loop. If no mouse actions are pending, this call will do nothing, and quietly return to your program. If you do not wish to support the mouse, you do not need to call this.
