Create/Release Clipping Mask and Brightness/Contrast, Black & White and
Gradient Map were written out by hand with the same body as
adjustment_event! or each other, which SonarCloud counts as duplicated new
code (photocraft's quality gate fails on 9.8% duplication from the GrpL
entry). adjustment_event! takes an optional command id, and clipping_event!
builds the two clipping events. The mapping table is unchanged.
