[PD] audio glitch/pause while redrawing array

it's really good to hear, that you are working on that... there would be
the possibility to add a thread on the pd side, that's sending the
messages to the gui ... the pd process adds the messages to a queue, the
helper thread sends the messages to the gui... more or less the same
thing i did for the soundfiler ...

that _is_ an interesting approach ... but in order to make this
threadsafe it would be possible to do this in a gui helper thread,
too...
i'd prefer loosing the syncronization between the gui and the dsp
kernel to gain a click-free performance :-)

cheers ... tim
