Thanks that works fine - obvious in hindsight and once you know matrix 
transforms are legit on the camera (as long as you don't have vista 
buffers - which I don't need but had for some legacy reason).

The end result is a rather odd optical illusion when you use it on a 
chequered plane, the squares further away look larger and the right side 
of the map looks more sloped.

I'm now playing with the matrix transform on perspective cameras, so 
I've now got many options for displaying the map :-)

thanks again
