Hi People,
        I'd like to put a watermark across the face of my graphs. My 
graphs are used by all and sundry across the globe and it causes some 
consternation for newbies to see times which are in advance of their own 
timezone, or show the possibility that the data collection mechanism has 
stopped ie the latest datapoint could seem to be 12 hours old.

Rather than do some weirdo stuff in the browser and cgi to set the TZ 
variable prior to generating the graphs, I thought a simpler method would 
be to use the "- - background" option to show that the graph was generated 
in a particular timezone.

So the question becomes - "How do I splat the words 'TIMESTAMPS ARE UTC' 
as a watermark style background to graphs of 595x222 size?"
