* This is a proof-of-concept sketch of a custom graph window,

 * for a p5.js library called Mathemagical.js. With a custom 

 * graph window, inputs to native p5 shapes are interpreted in

 * terms of a user-defined coordinate system. Mathemagical shapes

 * work the same way.

 *

 * The code that makes this sketch work can be found in the 

 * mathemagical-prototype.js file in this project's directory. 

 * That file constitutes an early prototype of Mathemagical.js.

 * Only a small sample of the planned features are currently 

 * included.
