[cairo] Getting Bezier Control Points from a Smoothing Function

[cecashon at aol.com]

Hi Lawrence, 

Lets say I want to draw a fish. So I work with a coordinate system and maybe use 0-1 or in this case 0-10 Cartesian. I sketch a general dot to dot sketch of my fish. Something to get me started. Then I can draw this sketch without trying to figure out where the control points might be. I can put something together quickly this way. Maybe, I can't quite get it how I want it doing this. At least I have the control points to work with. Here is a simple example of this approach.
