speed improvement in watershed calculation

JSL

Hi, I see that v20.1 has improved the viewshed calculation, and I know that contour generation was improved a few versions back.  I would really love to see improvement in the speed of watershed calculation.  I use a lot of high resolution DEMs, and I'm limited in the size of the window I can use because the computation power necessary for watershed generation process increases exponentially as I zoom out.  So if you're looking for a place to increase speed, this would be a great one!

Thanks...
