This file is in the public domain. This package is the collection of routines developed to facilitate traditional 2D graphics. It is incomplete, but still provides a reasonable amount of support. There is some support for 3D graphics here, but that is not so well developed. People are encouraged to improve these routines and add new routines.
All routines use list-based subscripting.
This allows programs to describe points as lists OR records. In the turtle graphics code, the use gives angles in degrees.
