I'm inclined to hedge and put the default povray.ini in
$prefix/etc/povray and all the others in $prefix/share/povray/ini. 
povray.ini is a system-wide default if nothing else is specified, so an
etc directory makes sense for that one, but I don't think it makes sense
for any of the others.  If there's an ini specific to a scene, it should
be in the same directory as the scene.  My $.02, anyways, unless someone
else points out a reason that this might be dumb.

That depends on what people are using all-scene.sh for.  POV-Win uses
scenes/incdemo/shapes.pov (at least, that's where that scene is under
Unix) for a post-install test; we could just render that for 'make
check' and keep allscene.sh as it is.  What do people think?

As for dependencies, you're thinking of crater.pov, which uses
crat_dat.png as a height field.  I've been meaning to fix all-scene.sh
so that it handles the dependency more gracefully.  One method would be
to turn it into a makefile (I would need to make it abundantly clear in
a README that it's not used for compilation; maybe I'll make life easier
and put it in a 'test' subdirectory or some such).

I'm not terribly surprised.

Not all Linux distributions have these, and not all have current
versions.  Might it be possible to check whether they have libpng and
zlib already and build them iff they don't?

Hmm.  Could we check the version of make with the configure script and
use a default tweak-it-yourself makefile if they're not running GNU
make?

Feedback from others? How many people aren't using GNU make?

I'd like to see something along these lines tested openly (broad variety
of platforms is vital for this, IMHO), and it's easiest to do that with
3.1 at this point.  If you're too busy, I can work on this myself, but
I'm looking forward to user feedback on this.
