--URGENT--
resend DMX on idle (artnet every 4s)

--REQUIRED--

* allow for finer grained channel control (set_block, set_channel)
* regression tests for plugins

--WISH LIST--

* consider using filters:
	o split dmx to different universes OUT = SPLIT(1,0,255)
	o invert channels OUT = INV(1)
	o different merge modes OUT = HTP(1,2)
	o change offset / map  OUT = OFFSET(1, +50)
	o scaler (OUT = SCALE(1, %40) )
	o clip (OUT = CLIP(1,%80) )
