727	Region for psImageCut	David.Robbins@…	eugene	"It's unclear from the SDRS whether or not psImageCut should function similar to
other related functions in it's interpretation of region coordinates. 
Specifically, indexing from the tail is currently unsupported and seems like it
should be.  Currently, we seem to be discussing/deciding on whether or not the
lower bounds (x0, y0) should allow indexing from the end.  However, in most
functions, at least the upper bounds (x1, y1) are allowed to use negative numbers.  
In ImageCut it also seems to be the case that the current implementation allows
for the upper bounds to be smaller than the lower bounds, ie, x0 > x1, etc.  I
am assuming that this type of behavior should NOT be allowed and it is simply
working this way by mistake?"	defect	assigned	lowest		PSLib	unspecified	normal
