attenuation that should really be optional. There's also a minor performance penalty and all this only for one problematic case. In case the tool flattens two surfaces, users can manually set the front face only option. A better non-attenuating way to cull such vertices can be added later. Also flatten brush should calculate the flatten plane from the original vertices or the flattening will not converge for planes offsets different than zero. Reported by Michalis Zissiou, thanks!
