START: Zoom patch (js)
The following javascript includes jQuery (http://www.jquery.com)
and adds zooming funcitonality to drraw quite similar to that
in cacti (http://www.cacti.net/image.php?image_id=36).
How does it work?
When the img-tag is rendered we add the current start and end
timestamp as unix-timestamp to the "axis"-attribute of that
img-tag.
On mousedown/mouseover we just draw a layer over the
image indicating that we are selecting a range. On mouseup
we then calculate the new start and end timestamp, fill
these values into the form and submit it.
