Borders
      The Borders Tab in the Features Toolbox
        contains options for display and selection of loaded and newly
        created borders on brain surfaces.  
    
      - Display
            Borders toggles border display on and off. When
          Border Mode
          is turned on, Display Borders is turned on by default.
      - Group: identifies the Border group for the Active
          Tab. Tabs assigned to the same Group will display the same
          borders with the same attributes. 
      - Borders
            Attributes contains options for viewing borders.
      
        - Contralateral check box toggles on display of borders
            that are currently being displayed on one hemisphere to be
            displayed on the contralateral hemisphere (on top of that
            hemisphere's own displayed borders, if any).
      
        - Draw As sets the shape of the border
            components (Lines, Spheres, Squares, Spheres and Lines).
      
        - Coloring sets the Class, Name, or Standard Color as
            the border color source.
      
        - Standard Color Selects the color when Coloring is set to Standard
            Color.
      
        - Line Diameter controls the border thickness
            if line is selected as the border component.
      
        - Symbol Diameter controls the size of the
            sphere or square symbol border components.
      
        - Unstretched Lines is used to correctly display a
            border from a 3D surface on a flat surface when the border
            crosses a surface cut from flattening. The distance
            indicates the limit for how much a border can be stretched
            across a cut surface before it is NOT displayed.
            Specifically, if the value of [(length of border on flat
            surface) / (length of border of 3d volume-interaction
            surface)] exceeds the Unstretched
            Lines value then the border is NOT displayed.
- Above Offset is
            used to move the borders above the surface with a positive
            value
      
    
      - Borders
            Selection controls group and individual display
          selection for borders. If a higher level
          group is selected on or off, all borders below that level will
          be similarly selected on/off. The All On/Off buttons allow for
          quick toggling of all borders on or off.
