---------------------------------------

Thanks Alex, I'm looking into this right now. I will do some further refactoring to keep the
old interface.

> New OverlayOperation that puts another image on top of the image used by the ImageOpReader.
Useful to overcome problems with browsers like IE that cannot put a transparent <img>
on top of a background image.
> Example usage:
>      <map:read type="image-op-overlay" src="background-image.jpg" >
>           <map:parameter name="overlay-offset-x" value="10" />
>           <map:parameter name="overlay-offset-y" value="20" />
>           <map:parameter name="overlay-source" value="overlay-image.png"/>
>      </map:read>
