What are the best tools/libraries (in any language) for working with 2D constructive area geometry?
That is, a library working with more or less arbitrary two dimensional shapes and supplying union, intersection, difference and XOR.
My baseline is the...

Two options come in mind
Cairo Graphics for C Antigrain for C++.
It had a commercial and an open source license last time I checked .
The Computational Geometry Algorithms Library is quite extensive.

I would solve it with the Flood fill algorithm.
Doesn't look like a geometry problem to me.
This should work.
