<!-- <img id="image" class="size" src="%s" />
Using tables, rather than div's to make use of the vertical-align style that <video id="video" class="size"></video>
doesn't work on div's. This avoids the need to do positioning manually which %s
could get messy when changing verses esp. with transitions
Would prefer to use a single table and make use of -webkit-text-fill-color
-webkit-text-stroke and text-shadow styles, but they have problems working/
co-operating in qwebkit. https://bugs.webkit.org/show_bug.cgi?id=43187
Therefore one table for text, one for outline and one for shadow.
