I think that cutting holes will not be necessary. Rules inside the
renderer would be a much better way to do this - if area A is
completely inside area B, then render the area as area A, or more
general, if something is a part of two areas, render it as the
smallest.

Unfortunately it seems the actual renderers seem to have taken a
different route, where in some cases the overlapping area gets a kind
of mixed colour, and in other cases some type of area always takes
precedence over another, even if it is a part of it, but I still think
that a rule as specified above would be the best way to go.
