[cairo] Thick paths redux [Hack solution]

[donn]

Hello list,
I include my python code for the solution I came up with. It took some 
googling and an eventual helpful answer on Stackoverflow.

http://stackoverflow.com/questions/133897/how-do-you-find-a-point-a-given-perpendicular-distance-from-a-line

The task:
Given a curve of 1px thickness, get a series of points around it such 
that they are all 'thickness' away from the curve. This is a kind of 
stroke-to-path thang.

I attach the relevant function, not the entire mess which I am still 
hacking on.

HTH,
\d
