[PD-dev] PD canvas interaction - flext GUI

[guenter geiger]

Hi Thomas, Krzysztof,

We had several discussions already about redesigning the pd<->GUI
comunication, I think that this in general is starting to be a bottleneck.

In my opinion more of the  GUI stuff should be done on the GUI side,
and not from within pd,... but I might be completely off topic with this ?
