The TIFF standard is a maze of twisty little chunks, all different.  It's
very hard to support it in a sane way.

POV 3.5 writes 16bpp PPM images in a way that the current version of netpbm
can work with them.  Netpbm, for its part, is capable of writing TIFF images.
This shouldn't be too hard to piece together.
