Hi,
Trying to figure out how to use the Voronoi library in 1.54 Boost (Great
stuff BTW, Thanks!)
I am using the library to shatter a 2d convex polygon.
So I need to generate polygons that are the results of clipping a voronoi
cell against my convex poly.
I am having hard time figuring out how to properly identify the direction
of the semi-infinite edge.

I know i can obtain the general direction of the infinite edge from the
participating cell points,
but I am not clear on how to distinguish between two possible directions in
the semi-finite case.

Any help would be much appreciated!
Thanks!
Nick.
