35	psImageWriteSection/psImageFWriteSection clarifications	robert.desonia@…	Paul Price	"psImageWriteSection doesn't have enough parameters to fully define an ""image
portion"" for an image.  Am I to assume the whole psImage is to be written into
the FITS file at location (x,y,z)?

If the given z is greater than the image cube in the file, is that an error or
should the image cube be resized (which could be a costly operation).  Can I
assume that the appropriate action for this is to be defined by the capabilities
of the underlying library (i.e., currently CFITSIO)?

What is the purpose of the return value of psImageWriteSection, as assumably it
does not modify anything but the file?  Is it just to communicate success?  If
so, why not just return an integer flag?

Can I assume that the extnum parameter is to be used only if extname is NULL?"	defect	closed	high		PSLib SDRS	unspecified	normal	fixed
