??? geometry::area works for all types.

So it also works for point_xy. If there is something not compiling, it 
is not because of the area.

I agree, this should be tried, but does that work for point_xy? I assume so?

I'm not sure if I understand you, but I've suggested compile-time 
parameters earlier and I thought it was not possible because you don't 
know the depth of rtree-levels before. Or do I confuse things?
