Thanks for the code. I believe lines 322-334:

private double boundAngle0to360Degrees(double angle)
    {
        // Naive algorithm
        while(angle >= 360.0)
        {
            angle -= 360.0;
        }
        while(angle < 0.0)
        {
            angle += 360.0;
        }
        return angle;
    }

could be replaced with

private double boundAngle0to360Degrees(double angle)
    {
        return(abs(angle)%360.0);
    }
