I'm repeating myself here, but I think what POV-Ray *really* lacks is a separate
option to explicitly specify the output image pixel aspect ratio.

From there on, the door would be wide open to all sorts of "automatic fixing" of
the residual aspect ratio issues.


Even your suggestion would not catch cases where a user may want to preserve the
original image's aspect ratio, but render for a different pixel aspect ratio.
