This operation has the following features:
RotateCommandFlags.Resample and RotateCommandFlags.Bicubic can be combined with RotateCommandFlags.Resize, but they can not be combined with each other.
If RotateCommandFlags.Resize is set, then the image is resized. Otherwise, the image is cropped.
Interpolation can be done while rotating certain images. This produces superior output, eliminating the jaggedness occurring when rotating images at angles that are not multiples of 90. (ie when RotateRequest.Angle is not a multiple of 9000).
