IMPORTANT - READ ME!

This file sets pokes around in the private API a lot to provide efficient

debug rendering given nothing more than reference to a Chipmunk space.
|

It is not recommended to write rendering code like this in your own games
|
||||
as the private API may change with little or no warning.
