EffectRainBow
EffectRainbow adds a rainbow to the image centered at the specified
coordinates and with a given radius. The center coordinates and radius
can be linearly varied during the effect by specifying the Final coordinates
and radius. Left and right cut off of rainbow display can be specified
and varied during effect. (these cutoffs were introduced as an user wanted these to
block the rainbow due to buildings).
RGB32, RGB24 YUY2 and YV12 color formats only are supported at this time.
