521	psImage.col0,row0 should not be const	eugene	David.Robbins@…	"psImage.col0,row0 are defined a const, but probably should not be.  If you want
to create an image which refers to a subregion of a non-existent parent, it is
necessary to set col0,row0 by hand, since in this case, you could not use
psImageSubset.

This was defined const in the SDRS for v.16; I've changed the SDRS, the code
should be changed to match."	defect	closed	high		mathtypes	0.7.0	normal	fixed
