  DPI with regard to what? POV-Ray creates an image of x*y pixels (specified
by the user). What on earth could a "DPI" value affect that x*y pixels image?

  A DPI value is used for example by a printer to *scale* an image when
printing it. If you print a 1024x768 image at 300 DPI the printer will
scale the pixels larger than if you print it at 600 DPI. The contents
of the image will not change, only the size of the pixels in the paper
(ie. lower DPI -> bigger pixels).

  POV-Ray just renders an image with certain amount of pixels (which you
can specify). Whatever you do with those pixels afterwards is completely
up to you. If you want to print them at 600 DPI there's nothing stopping
you from doing so. Just do it.

  I can't even start to imagine how a DPI value should change the output
image created by POV-Ray. After all, the image resolution is in pixels,
not in inches.
