That will have problems with geometric features that are smaller than
the cells i assume. Still a clever idea of course - it will improve
performance for thing like trees but if the orthographic view is nearly
totally white a conventional sampling of the whole area would be more
efficient.

That's the case for *rendering* but not for *parsing*.
