Ok. So I could get the Bbox extent from the polygon? It seems to me
that it is not possible to make this selection through anything
different from a rectangle..
I mean: if my polygon is a rectangle rotated, how could I calculate
the bbox extent? But anyway this would be a minor issue, if I could
get the bbox extent. Cold I make this calling the toBBox() function on
the polygon? Of course I should have one polygon at a time..
If this is not implemented, wouldn't it be a useful feature?
