docs: /*
  (copied from the Google API docs) Sets the state of a drawable to match a given state bitset.
  This is done by converting the state bitset bits into a state set of R.attr.state_pressed,
  R.attr.state_selected and R.attr.state_focused attributes, and then calling {@link
  Drawable.setState(int[])}.
