*** ** * ** ***

This class contains the rules for updating the bounds of a[CompositeDrawable.ChildDrawable](https://developer.android.com/reference/android/support/v17/leanback/graphics/CompositeDrawable.ChildDrawable). It contains four rules, one for each value of the rectangular bound - left/top/right/bottom.
