What does intrigue me is the issue of layers containing 2 or more types of object.
If you're going to allow points, lines and regions to be stored together (sometimes useful though its a no-no from a database point of view), why wouldn't you force points to draw on top of lines on top of regions ? If this "redraw order by object type" functionality was implemented, then it would make multi-object-type layers useful for map annotations.
