After seeing OpenEXR in there, I'm almost wondering if TIFF input support
isn't a bit of a third leg, especially given the library compilation
issues. Is there anything TIFF can do, that the other supported formats
can't do better and in a more standardized form---at least for the set of
features that POV-Ray can use?

It seems to me that one could realistically discuss deprecating (and
eventually dropping) TIFF support from POV-Ray, to move away from what has
always been a problematic format (and library). Image map files could be
converted to another form without any loss in the process. Of course,
backward compatibility with old scenes would be an issue, and I'm not aware
of what the policy is on this beyond the #version source-compatibility
directive.
