// <synopsis>
// QtDisplayDataGui is a thin layer over a QtAutoGui base, to
// provide the options widget for a single QtDisplayData.  It is normally
// in a tab of a QtDataOptionsPanel.  Unlike QtAutoGui, which is
// intended to be generic and reusable for other purposes, QtDisplayDataGui   
// knows about a QtDisplayData; QtDisplayDataGui makes the communication
// connections between its QtDisplayData and QtAutoGui.
