The first two values of 'setbounds' are the same as 'pos', they are  
the upper left corner.  But you have to also set the   lower right  
too.  This message is not really meant to be used a lot externally.   
Its really a direct mapping of the data that Tk gives to the format  
that Pd saves in the .pd file.  Plus 'setbounds' doesn't even take  
effect until you close and open the patch again.
