112	psImageSlice	robert.desonia@…	Paul Price	"Upon implementing psIamgeSlice, I'm abit confused about exactly what you want. 

You have a direction enum that not only specifies which axis to slice in (which
is clear enough), but a positive or negative direction as well.

Does this pos/neg component effect the region, i.e., for pos, the region is
(x,y)->(x+nx-1,y+ny-1) and for neg, it is (x,y)->(x-nx+1,y-ny+1)?  If so, why
not just pass in negative nx and ny values to signify this, as it is logically
cleaner?

If that is not the proper definition of things, then does it just specify the
direction in which the vector is populated, i.e., the lowest row/col index in
the slice is the end of the vector?

If nx and ny allowed to be negative?  If so, could we not redefine the function
to eliminate the POS/NEG concept in that case? (if you want to go 'NEG', pass in
the lower right corner of region as x,y and use negative nx,ny).
