Bug Description
With the Smalltalk Sketch "Chaotic Sequence", modifying the code as bellow:
n / 5 @ (2 * r value * value * (1 - value))
makes the VM to hangs and optionnaly to crash. Then the terminal shows this repeated list of messages:

When simulating exponential growth, drawing positions can be crazy.
I implemented detecting for those situations with point and polyline objects (segment, ray, polygon, locus, etc). so this "Chaotic sequence" Smalltalk sketch pass.
It should be implemented for circle, arc and angle too.
