I have not tested it, but maybe your differences come from the fact that
you use version 3.8 here. I did not, from the principle that version 3.7
and/or 3.7.1 are the /last/ official versions of POV-Ray. As a start,
the includes should comply with those versions. Version 3.8 is beta and
may need more changes in future.
