Plasma function creates a plasma of changing colors on the image.
The x and y coordinates, width and height of area in which plasma appears
can be specified and varied linearly during duration.(possibly
useful if a plasma was to be introduced in a photo frame and camera moves.)
Or it can be created fully covering image. The color tints displayed
can be varied by tint parameter.
RGB, YUY2 and Planar 8/ 9-16/32 bit depth formats are supported. Thread Safe.
