They don't have to.  Given any two of the three parameters, POV could
calculate the third.  If I say I want an 8"x10" at 300 DPI, POV could
easily figure out that I meant +W2400 +H3000.  Contrariwise, if I say
this 2400x3000 image should be 8"x10", POV would figure out the 300 DPI
part for itself.  In either case it would write a DPI=300 header into
a 2400x3000 image.  The only problem would come when someone indirectly
specifies a DPI that the service bureau can't handle directly, like 216
or something.  That's a wetware issue, though.
