From efe9e323ccfcdb4186d900ad29a14b189d1ad1d6 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Added support for a <video> tag. This tag works similar to
 the <image> tag, but has an additional numLoops attribute to indicate the
 number of times the video should be looped. The default value is
 numLoops="1", and you can use numLoops="0" for infinite looping.
