Raster Seed Tool

Discussion created by ryansc on May 22, 2014
In 3.1 there was a 'Seed Tool' that would allow me to pick a cell in a raster and a variation factor that would expand the selected area and create a polyline/polygon.  I routinely digitize waterbodies and this made it very convenient to quickly delineate a boundary where the water met the shore.  Is there a readily available code to accomplish this?
