Are you 100% sure about this? Usually the stair effect is caused by a lack
of anti aliasing. Rendering the image at a huge resolution then doing a
resize with proper resampling is more or less equivalent to enabling
anti-aliasing, but this should not be necessary - proper anti-aliasing can
use certain optimisations to make the process more efficient.

(...) After looking closely at the forklift image, I think the stair-step effect is happening due to POV-Ray's adaptive antialiasing algorithm. It's much quicker to render the image at the desired resolution with adaptive antialiasing enabled in POV (...) (22 years ago, 30-Sep-04, to lugnet.cad.ray)
