Simple byPass that uses the "alternative" input when "input" is absent (nothing plugged) or under a threshold (0 by default).
Typically you can use this node for inputs or optional inputs in your own shared nodes. The user plugs nothing or a black image, but you need to have something that isn't pitch black, in order to have a good behavior of your node.
Also, if the highest value of your grayscale input image is under a threshold (only parameter of the node), the alternative is used. It can be useful inside nodes for quickly (and automatically) change grayscale images.
Sorry for the name of the node, I'm very bad for this. ^^ You can talk about this node here: https://forum.allegorithmic.com/index.php?topic=12802
Important update 25/09/2016: Now you can use this node is highest resolution without crashing/freezing, due to a huge improvement of some dependencies. And much faster, like 200x faster with 2K heightmaps.
