d7078f3623 Layers: a new empty layer no longer recomposites every layer (#1846)
step_damage pairs layers by id and steps over a layer only one side has when it draws nothing
(an empty pixel layer or group in Normal/Pass Through, no masks, effects or Advanced Blending,
not a clipping base), so New Layer, New Group and their undo/redo report no damage. Adds the
P51 perf scenario (new layer in the 150-layer document). Fixes #1771.
