    Fix compiler error with SetHFOV
    
    In gazebo7, the rendering::Camera::SetHFOV function
    is overloaded with a potential for ambiguity,
    as reported in the following issue:
    https://bitbucket.org/osrf/gazebo/issues/1830
    This fixes the build by explicitly defining the
    Angle type.
