[cairo] RFC: Possible tutorial prgram

[Scott Robert Ladd]

I'm may write a Cairo tutorial, based on what I learned while writing 
the program found here:

    http://www.coyotegulch.com/distfiles/unit_circle-1.0.0.tar.gz

The program isn't rocket science; one of my home-schooled kids had 
trouble understanding the relationship of angles and trig functions, and 
I needed a small project for getting better acquainted with Cairo.

If anyone on the GTK or Cairo teams has comments about the code or
improvements thereto, I'm open to suggestions.
