[Radiance-general] super high res images

[Jack de Valpine]

Hey Greg,

I could probably do the large image straight off. But since I have never 
tried it, I am trying to consider contingencies.

So alternatively, tiles could be generated seperately, pcomposed 
together and then filtered down to avoid tile boundaries.
