// Class: QvisPointControl
//
// Purpose:
//   This is a widget that encapsulates the individual point control
//   buttons into a Point controls widget.
//
// Notes:      
//
// Programmer: Kathleen Bonnell 
// Creation:   November 4, 2004 
//
// Modifications:
//   Brad Whitlock, Thu Dec 9 17:01:35 PST 2004
//   I replaced the line edit for the variable with a variable button.
//
//   Brad Whitlock, Wed Jul 20 13:44:39 PST 2005
//   Added a control for setting the point size in terms of pixels for
//   when we render the points as points.
//
//   Brad Whitlock, Thu Aug 25 09:29:56 PDT 2005
//   I changed the point size from a button group to a combo box.
