BTW, for ggl::overlaps, wouldn't AND'ing be more efficient than OR'ing?

If I had to write an optimized compiler, I'd say that if the first condition
of a AND is false, I'd bail out with FALSE without testing the other
conditions, while OR'ing means you systematically have to test all
conditions....
