How would one go about figuring out the mathematical area (xxx units
squared) of a closed vector path?

Note: These paths will not be simple little boxes or circles.  Think
complex paths--composed of mulitple line segments and arc segments
(both convex and concave).

I use the GLU Tesslator (part of the OpenGL GLU library) to decompose the complex path into a series of triangles. Once you've got triangles, the area is trivial. Of course, this isn't as mathematically accurate as handling the curves directly, without a polygonal approximation.
