Here comes a dreadful hack. How do we determine if this rotation of the base image has already
been loaded? The image names contain no identifying information, they are just numbered sequentially.
So the rotated name is EMFrotimage###_XXXXXX, where ### is the number of the referred to image, and
XXXX is the rotation in radians x 1000000 and truncated. That is then stored in BASE64 as the "image".
The corresponding SVG generated though is not for an image, but a reference to an image.
The name of the pattern MUST stil be EMFimage###_ref or output_style() will not be able to use it.
