Polygon Union


I am looking for a Mathematica function which generates the union of
two (not necessarily convex) polygons.  I found a package on the web
(the Imtek library, I believe) which includes a convex polygon
intersection function, but not a polygon *union* function.  Does
anyone know if such a function is available or, if not, can anyone
suggest an algorithm to implement in Mathematica?

Thanks in advance,

David Skulsky
