link.to.self.for.mediaobject boolean
link.to.self.for.mediaobject Include a element to image objects itself to go to a full-size, freely-zoomable version

## Description

In some cases, it can be very helpful to be able to click on an embedded figure or informalfigure to get a full-size, freely-zoomable version of an image, for instance when targeting readers on smartphones. This is implemented for images only, but not for audio or video objects.

If non-zero, the image will be wrapped in an a element, using the href attribute pointing to the image itself:

    <a href="source/image">
       <!-- the image object -->
    </a>

If the value of link.to.self.for.mediaobject.xml is zero (default), then no a container is added.
