* Brush input mappings now have three inheritance mode: "always", "never" and "channel" (use channel's inheritance mode). * Note that the UI exposes a single inherit icon, which just toggles between "always" and "never," to lessen user confusion. * Brush mappings default to "never" inheritance mode. * Fixed wrong node update flag in bke_pbvh_insert_face_finalize leading to disappearing parts of the mesh.
