ImageOp: overlay a transparent image on another one
---------------------------------------------------

                 Key: COCOON-2048
                 URL: https://issues.apache.org/jira/browse/COCOON-2048
             Project: Cocoon
          Issue Type: New Feature
          Components: Blocks: (Undefined)
    Affects Versions: 2.2-dev (Current SVN)
            Reporter: Alexander Klimetschek


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>
