// Method: QvisTransformWindow::GetCurrentValues
//
// Purpose: 
//   Gets the current values for one or all of the lineEdit widgets.
//
// Arguments:
//   which_widget : The number of the widget to update. If -1 is passed,
//                  the routine gets the current values for all widgets.
//
// Modifications:
//    Kathleen Bonnell, Wed May 21 11:06:13 PDT 2003 
//    Disallow (0, 0, 0) as the rotation axis.
//
//    Jeremy Meredith, Tue Apr 15 13:42:44 EDT 2008
