Description
Attempting to read an image with bitpix=16 and bzero=32768 produces the
following error:
2005:01:04 01:04:49Z|mithrandir |E|psLib.image.psImageReadSection
FITS image type, BITPIX=20, in file GRB041219c-001V.fit is not supported.
Of course, the FITS file isn't really bitpix=20, but cfitsio calls it that
internally when using fits_get_img_equivtype (see fitsio.h, search for
USHORT_IMG). However, this fools psImageReadSection into thinking that the file
has an unsupported value of bitpix, and so it fails unnecessarily.
Example FITS files can be provided on request.

Looks like a mistake was made in commenting out some lines that support that
type of data.
Attached is the src/image/psImageIO.c file with the "Not a Requirement" marked
lines uncommented.

Changes to psError mean that I'm having trouble building it (I'm guessing the
attachment is from the mainline, not rel3). I'll test it later in rel4.
