Perfect! That was exactly what I was looking for, and I've now got the osm2city
buildings working with the default pipeline under the Compositor.

I noticed in passing one oddity - the wiki suggests using technique number 10-19
for ALS, but model-combined.eff uses technique 4 for ALS with the model shader.

I'm also getting a crash when using --compositor=Compositor/als,
stacktrace below.
