OPERATOR
rotate --- rotate an image by an arbitrary angle
DESCRIPTION
The rotate operator performs an arbitrary rotation on its input image. The
angle parameter defines the angle in degrees where positive angles represent a
rotation counter clockwise. This operator will enlarge the overall size of the
input image to accomodate the new spacial location of objects in the image
as they rotate. The enlarged image requires the background regions to be
filled with an appropriate value. This value is computed as the average of
the four corner pixels in the original image.
