Subject: [boost] Adapting Polygon to work with point attributes
From: Paul Miller (paul_at_[hidden])

Boost::Polygon looks like exactly what I need to do some boolean
operations on polygons but my polygons have additional attributes per
point that I want to carry through the operation. But I can't figure out
how to get polygon to create sensible values for the attributes other
than X,Y, and I can't find an example that covers this scenario. It
seems from the documentation that this is possible however. Can someone
point me to an example, to say, adapt a polygon with this Point type?

struct Point {
     int x, y;
     float r, g, b, a;

Ideally it would average new r, g, b, a values together to make new
points and polygon join points, but it could just copy one of the
existing Points' attributes instead. I'm not picky.
