EffectBinoculars
The EffectBinoculars function creates twin magnified circular
windows touching each other and can be panned. The radius of viewing disc,
co-ordinates of the center point of the line joining the disc centers
(and final co-ordinates) are to be given. If final co-ordinates are omitted,
the view remains stationary at initial co-ordinates. The end magnification
can also be specified. It can give a zoom effect if properly used.
The co-ordinates must be specified within limits that ensure both the discs are
inside frame.
RGB32, RGB24 and YV12 formats only are supported
