All these *are* already on the rendering; the rendering is based on
plain z9 tiles which are just bitmap reduced. They're just not prominent
enough. Using a few simple tricks a la
http://www.remote.org/frederik/tmp/tiles/ the roads could perhaps be
brought out more. Of course I could also simply not render landcover at
all at z9.

I don't think that would work with the bitmap approach.

No, it was relatively benign, took my tile server a few hours to make
the base tiles on z9 and then the rest was easy.
