I think this would be good enough for the first version; then if we decide to do something like the subdivision Jason suggests, we can do that later. (I don't think there would be much wasted work... most of the effort for just tossing the triangles should be in documentation, plumbing the region function into .triangulate, etc.; and all of that work would presumably still be useful in a more elaborate implementation.)
