Sets rotation options for the image, whether to rotate by a multiple of 90 degrees, use the
EXIF metadata (relevant to JPEGs only) or to not rotate. This also specifies whether the
rotation should be left until the bitmap is rendered (as the GPU can do this more efficiently
than the effort to change the bitmap object).
