[PD] 'synced' number and slider

[Jonathan Wilkes]

I attached a modified version of your patch to show what I mean.  On the 
right, you can look at the patch and figure out the behavior before you 
scroll the gatom box (important if you want to make sure you're avoiding 
a buffer overflow).

On the left, you have to read the source code for those GUI objects to 
figure out what's going to happen.  Judging from your original patch, 
I think you assumed that sending a float straight to the [nbx] would 
update the value in the slider (so did I).  This turns out not to be the 
case: the two GUIs are only bound together if you change the values on one 
of them using the mouse.

If someone who reads and understands c better than me can explain why 
the iemgui magic works as it does, I'll be happy to document it.
