While there are still many things I can do to increase the capabilities of AM TerraForm, I have already exceeded what I originally set out to accomplish 10 months ago, so I'm calling version 1 complete. This version was mostly for giving the community something they were asking for and for gauging what the community might be willing to pay for the effort involved in creating it. Given the almost complete lack of monetary interest on the part of the AM community for further development, I can't say for certain what will happen to it in the future - for the moment it's done.
New in this release is Undo/Redo for the Smoothing option. I have also included an fBm-type fractal that I'm calling Neo fBm (for want of a better term). It's the same as fBm but allows you to control the incidence of white pixels in the generated image for landscapes that have few, if any, really high points.
