```
    Compute the angle of the Center Of Sector line. The center sector angle is computed as the average of the left and right azimuths of the last range fan in the graphic. MIL-STD-2525C does not specify how this angle should be computed, but the graphic template (pg. 693) suggests that the Center Of Sector line should bisect the last range fan arc.
    
    Parameters:
    
    finalLeftAzimuth - Left azimuth of the last range fan in the graphic.
    
    finalRightAzimuth - Right azimuth of the last range fan in the graphic.
    
    Returns:
    
    Azimuth, from North, of the Center Of Sector line.

```
    Create positions to draw an arc around the graphic's center position. The arc is described by a radius, left azimuth, and right azimuth. The arc positions are added onto an existing list of positions, in left to right order (the arc draws from the left azimuth to the right azimuth).
    If the left and right azimuths are equal, then this methods adds a single position to the list at the desired azimuth and radius.
    
    Parameters:
    
    dc - Current draw context.
    
    radius - Radius of the circular segment, in meters.
    
    leftAzimuth - Azimuth (from North) of the left side of the arc.
    
    rightAzimuth - Azimuth (from North) of teh right side of the arc.
    
    positions - List to collect positions for the arc.
