ENGR00126698 - EPDC fb: Pan API should not trigger full screen update
In order to provide more flexibility to the user, the pan API should not
automatically trigger a full-screen panel update. No update will
be performed, and the user will have to submit a SEND_UPDATE to update
the screen after panning.
