This class is the manipulator class for a point on a surface.
The manipulator has a position handle and tangent handles in
both the U and V directions. When the user clicks and drags
on the position handle, it moves in u-v space, based on the
intersection of the cursor with the surface. When the user
clicks and drags a tangent handle, the manip is constrained
to move along that u or v direction only.
Because this class has to perform ray-surface intersections,
there are utilities to GIVE this manip a TraySurfaceIntersect
object to use, instead of this class continuously allocating
and freeing a TraySurfaceIntersect of its own.
