I suppose the real question is: Do we want to make the various libraries
in lib dependent upon lib/gis or should they be as independent as
possible?

Rewriting the lib/image error routines are simple enough, so either way
works for me.

AFAIK, lib/ogsf is the only usage of lib/image.  The biggest reason I
started working on lib/image was to allow lib/ogsf to compile without
explicitly adding -fPIC to compiler flags.

PS -
Oddly, lib/image has been kinda fun to work with.  Reminiscent of
writing video card kernel drivers and I learned the header format of a
SGI IRIS images.
