/* TEACH GO_ROTATABLE                          Ben Rabau, 27th Aug 1993

This file refers to the go_rotatable mixin which allows rotation of
screen objects in GO. This class is used as an extension for the basic
go_located mixin.

The rotatable objects will use an extra method to set the angle of
rotation, go_angle(), and an extra position around which the object
rotates, (go_xrotation(), go_yrotation()).

See TEACH * GO_LOCATED and TEACH * GO_POLYGON for examples and usage
of this mixin.
