The shapes 'gear6' and 'gear9' need very special methods to
calculate the adjustment value from the handle position. Inserting
these methods shifts the other cases one level down, therefore the
patch looks large. The gear6 and gear9 shapes do not fit to the
common test pattern, so they are not included in the unit test.
