Reg_Polygon is defined in
is derived from
Polygon, using public derivation.
As noted above in Polygon Reference; Affine Transformations,
currently inherits its transformation functions and
operator*=(const Transform&) from
the data members of a
Reg_Polygon, except for
not recalculated when it's transformed. I plan to change this soon! It
will also be necessary to add the function
Reg_Polygon::is_reg_polygonal(), in order to test whether a
Reg_Polygon is still regular and polygonal.
