Trim Sphere

Trim tool: used to quickly flatten large portions of the world

Best results are obtained when Position and Normal are averages: use FindProjectionVoxels to do some linetraces, and then GetAveragePosition/Normal on the result

This ensures the tool usage is relatively smooth.

Works by stamping a shape into the world (if bAdditive = false, the stamp is destructive: voxels are removed instead)

The shape is the smooth union of a sphere SDF and a plane SDF. The smoothness of the union is controlled by the Falloff parameter.
