1. Preferred polygon-to-rectangle clipping algorithm?

For a current project, I need to be able to clip a polygon to a
rectangle, and find the smaller rectangles which lie either inside or
outside the polygon.  I figured this could be done with a
polygon-to-rectangle clipping algorithm.  My copy of Foley et
al. reviews the Sutherland-Hodgman and Liang-Barsky algorithms.
However, this book is now 6 years old.  Any more recent developments
that should be considered?

Thanks very much.  Please cc or e-mail responses, as I don't get to
check these newsgroups often.

Thanks,
