I've noticed a difference in behavior when passing channel
data in APPCULL_DRAW verses APP_CULL_DRAW multiprocess modes.
It works as expected in APP_CULL_DRAW, but in APPCULL_DRAW
you must force the creation of the channel data buffers with
three calls to pfPassChanData (chan) & pfFrame(). If you don't
the data pointer is null in the draw callback. Is this correct
or am I not setting it up correctly in APPCULL_DRAW mode?
