Never mind, it wouldn't work anyway.
The problem is that "point @ box" isn't an rtree-indexable operation.
You could use "box @ box" instead, where the lefthand box is a zero-area
box with all corners at the point of interest. Crufty, but unless you
want to go in and teach rtree about a new operator type...
