Fire function creates a raging fire on the image. The x and y
coordinates, width and height of fire area can be specified and varied
linearly during duration.(possibly useful if a fire was to be
introduced in a fireplace.).
RGB, YUY2 and Planar 8/ 9-16/32 bit depth formats are supported. Thread safe.
