While technically correct that's misleading because there's a lot of stuff
happening on the 'pd' side
that a reasonable person would assume to be handled on the 'pd-gui' side.
Well, more than that--
there's stuff happening on the 'pd' side that doesn't need to happen at all,
but it can use massive
amounts of CPU and consequently a reasonable person gets dropouts when moving
an array that
has only 100 points visible and erroneously thinks, "Wow, I get dropouts just
moving some
polygons around on the screen? Tk stinks!"
