Handles an individual page.  For now, this marks up
canvas entities in a &lt;div&gt; tag.  Based on the spec,
it currently relies on order within the xml for order of output
of text to xhtml.  We could do more complex processing of coordinates
for bidi-languages, but the spec implies that we should be able
to rely on storage order.
<p/>
As with our PDFParser, this currently dumps urls at the bottom of the page
and does not attempt to calculate the correct anchor text.
