[PD] GUI overload

Hey Ed,

I just committed a couple more fixes for [tgl] and [mknob] that make them only
send the GUI updates when something actually has changed.  This can greatly
reduce the amount of traffic to the GUI.

Can you try your patch with the 2012-12-28 build of Pd-extended and see if you
still get freezes?

I am wondering if there is a specific limit to GUI objects that could be changed. I think Pd is making some kind of decision that "there's too much of this stuff - I'm gonna prioritize the audio and not worry about it" and I'd like to know how or if it is possible to control this process from within Pd, or by setting flags on the command line.

Example patch enclosed to give you an idea. The really GUI-intensive objects are the trackers, especially quadtracker (which I think has pushed the GUI of Pd patches about as far as I can go now).
