// An ink drop ripple that starts as a small circle and flood fills a rectangle
// of the size determined by |host_size| and |clip_insets| (if provided). The
// circle is clipped to this rectangle's bounds.
// Constructors take |host_size| and |clip_insets| and calculate the effective
// bounds of the flood fill based on them. This way, the ripple's bounds are
// defined relative to the host size and can be recalculated whenever the host
// size is changed.
//
// The valid InkDropState transitions are defined below:
//
//   {All InkDropStates}      => HIDDEN
//   HIDDEN                   => ACTION_PENDING
//   HIDDEN, ACTION_PENDING   => ACTION_TRIGGERED
//   ACTION_PENDING           => ALTERNATE_ACTION_PENDING
//   ALTERNATE_ACTION_PENDING => ALTERNATE_ACTION_TRIGGERED
//   {All InkDropStates}      => ACTIVATED
//   {All InkDropStates}      => DEACTIVATED
