I can see the point you (the organizers) are making, but I'd still like to
note that the printable image will probably be rendered separately anyways
(Rules 5Biii & common sense).  In other words, a trick like

height_field { function image_width*2, image_height*2 { ... } }

would give an optimal solution, namely allowing the entrants to do the very
best their hardware allows while still providing the organizers with full
detail of the print-quality images modelling -- with everything still
re-produceable from the same source data. In fact, I could even see this as
a technical merit and a good demonstration of POV-Ray flexibility when
designing images of great complexity.

I'm not trying to say how you should run the competition, and I will gladly
comply with any rules you deem necessary.  Just pointing out that with the
versatility of the SDL, loopholes in *any* set of any rational rules are
unavoidable; and that these restrictions about print quality are, in my
opinion at least, a MINOR issue when considering that the competition is
about production of some darn amazing ray tracings.

Having said that, I hope a good picture will win!
