docs: Defines the direction of the scale. The values are
  CLOCKWISE and COUNTER_CLOCKWISE. This property is needed
  to realize gauges like in QuarterSkin where the needle
  and knob should be placed on the upper right corner and
  the scale should start at the bottom. Here you need a
  counter-clockwise direction of the scale.
