Dang... Question now is whether we fix this for the specific renderer, or is this an osmbuildings bug... heh.

I know we aren't supposed to draw for the renderer, but even f4map rendering has problems.  I guess this would be hard to answer which is "correct".  I pretty much gave up on 3d buildings after another building I tried to draw - and it shows up differently in f4map and osmbuildings.  Tough to satisfy both!

re-closing since you were happy with the current results, but now after looking at it in osmbuildings it's leaving an OCD problem in my mind to fix it again...outside of this note...
