This makes it possible to restore previous Blender 4.3 behavior of bump mapping, where the large filter width was sometimes (ab)used to get a bevel like effect on stepwise textures. For bump from the displacement socket, filter width remains fixed at 0.1. Ref #133991, #135841 Pull Request: https://projects.blender.org/blender/blender/pulls/136465
