 // Because a single save/restore state can have multiple clips, this class
 // stores the stack depth (fSaveCount) and clips (fDeque) separately.
 // Each clip in fDeque stores the stack state to which it belongs
 // (i.e., the fSaveCount in force when it was added). Restores are thus
 // implemented by removing clips from fDeque that have an fSaveCount larger
 // then the freshly decremented count.
