EffectLens
EffectLens function magnifies a specified circular disc area. The
magnification can be constant in the disc or vary from center to edges
( drop=true). The lens center moves from the initial center coordinates
in pixels to the final coordinates.
RGB32, RGB24, YUY2 and YV12 formats only are supported

#Usage examples:-
EffectLens(last,51,158,60,5,40,240,400,240,false)
For stationary lens position, uniform magnification:-
EffectLens(last,51,158,60,5,40,240)
For stationary lens, varying magnification:-
EffectLens(last,51,158,drop=true)
