This abstract class is used by Drawables to store shared constant state and data
between Drawables.

Remarks
This abstract class is used by Drawables to store shared constant state and data between Drawables. BitmapDrawables created from the same resource will for instance share a unique bitmap stored in their ConstantState.
#newDrawable(Resources) can be used as a factory to create new Drawable instances from this ConstantState.
Use Drawable#getConstantState() to retrieve the ConstantState of a Drawable. Calling Drawable#mutate() on a Drawable should typically create a new ConstantState for that Drawable.
