displacement bug with the pow function a possible feature

[CTZn]

A displacement function embedding a pow can lead to no geometry at all. Please note that I'm interested in the feature (water ponds, based on terrain displacement).

off the top of my head, triangles will vanish if the displacement signal is using a pow function with an exponent below 1.0. I experienced this in multiple occurrences.

again, nuking triangles by a boolean function would be a cool feature.
