The duration in seconds of a fade operation or a fade hardware reservation.
Declaration
typealias CGDisplayFadeInterval = FloatDiscussion
Quartz uses this data type to specify the duration of both fade-out and fade-in operations. Values may range from 0 to kCGMaxDisplayReservationInterval seconds. A 0 value means fade immediately—see CGDisplayFade(_:_:_:_:_:_:_:_:).
