if not then typically they come with a companion viewer (Spry has done this, 
but i pity the fool who buys that piece of crap) ... and then i would say it 
would be up to the user to figure it out (enough hand holding already; those 
who are serious about viewing the visual beauties youse guys create will by 
their very nature obtain decent software)....
not quite 2 cents-
