Rotates the image by degrees according to the value specified.
Valid values are in the range
359, and rotation is counter-clockwise with
0 (the default) at the top of the image. The image will be zoomed after rotation so that it covers the entire specified dimensions (unlike
orient, which keeps the image at the same zoom setting and rotates the frame along with the image).
See the API specification for more information about this parameter's value ranges and format.
