RasterMouse.addTimerListener( callback, arg )
Register a callback function to be called at periodic intervals during the duration of a drag operation. The callback function can introspect the mouse position and implement auto-scroll behaviors in a control.This method has no effect if invoked when no drag operation is in progress. The callback function will have the following signature:
//////////////////////////////////////////////////
// mouseEvt: a RasterMouseEvent
// arg: the 'arg' parameter
function myCallback( mouseEvt, arg )
{
//...
}
The callback function will stop being invoked when the current
drag operation ends.
