It has been brought to my attention that the XROI demo
in the IDL demo distributed with IDL 5.5 does in fact
have a button that allows one to set the "Region Grow"
properties of the ROI. Apparently the demo takes
advantage of a new function in IDL named (oddly enough)
REGION_GROW. You can read all about this in the on-line
he...er, well, you can read all about it somewhere (I'm
sure).

Apparently REGION_GROW does much of what SEARCH2D
used to do, but adds the capability of doing it
in 3D, something my ...uh, wife found interesting. :-)

Cheers,

David
