DESCRIPTION
     SbCylinderSheetProjector projects a window space point (usually based on
     the mouse location) onto the surface of a cylinder with a hyperbolic
     sheet draped over it. This allows smooth transitions onto and off of the
     cylinder.  Two projected points can produce a rotation along the
     cylinder's axis. When the mouse position projects on to the sheet, the
     rotations will be as if the sheet is being dragged, causing the cylinder
     to roll beneath it.

     Incremental changes (delta rotation) can be computed during interactive
     sessions. Cylinder projectors are typically used to write interactive 3D
     manipulators and viewers.
METHODS
                         SbCylinderSheetProjector(SbBool orientToEye = TRUE)
                         SbCylinderSheetProjector(const SbCylinder &cyl,
                              SbBool orientToEye = TRUE)
          Constructors. The first uses a default cylinder aligned with the Y
          axis with radius 1.0; the cylinder is supplied in the second. The
          orientToEye parameter determines whether the sheet is perpendicular
          to the eye, or perpendicular to the cylinder's Z axis. Setting that
          parameter to TRUE (the default) specifies that the plane be
          perpendicular to the eye, which is most often the desired behavior.

          The default view volume is undefined, and the working space is
          identity.

                         ~SbCylinderSheetProjector()
          Destructor.
