I thought about this, and I am going to try this approach next, since I
don't have the time to implement the proposed extension of mkgmap by myself.

But this solution will not help the POI problem.

And the solution is also much less flexible: You have to decide before
the map generation, which items shall be drawn on which layer. And you
also need to decide before, how many layers you need. I think my
proposal is much more flexible if you have different combination of
multiple items (e.g. a street is on a bridge, has a cycle lane and is
part of an relation)

And I don't know, how the Garmin devices handle multiple transparent
maps, In mapsource you always get only one map at a time.
