An improved slope selector that is more consistent between different resolution builds
The Stable Slope Selector improves upon the behavior of the default Slope Selector.

Slope selections are very sensitive to noise in the heightfield. An area that is gently sloping in a low-resolution heightfield may well be rough and irregular in a high resolution one. This is a common occurrence with fractal-based heightfields which are noisy at fine scales.

The example image shows this: The normal selector yields a totally different looking mask using a high resolution build than a low res one.

This selector smooths the heightfield before the selection, making it more consistent regardless of the resolution of the build.
