SlopeBlur Carving

I always loved using Blur in designer, especially the SlopeBlur !
While thinking on how to speed up my creation workflow :)
I ended up creating new nodes to speed up my workflow and to quickly carve shapes.
For example starting from a basic noise (FractalSumBase, Perlin, ...) after each iteration of the node the shape will be cut and become more define and sharp.

With just a few other options we have interesting variations.
Useful to have a quick 1st pass on shapes.
