TerrainManipulator does terrain intersections to control the center of
rotation, while the SphericalManipulator is not bound to any model and
is more like the TrackballManipulator save for the interaction model.
We should try to keep naming consistent where possible though -
TerrainManipulator has a enum:
enum RotationMode
{
ELEVATION_AZIM_ROLL,
ELEVATION_AZIM
};
