beware nodejs garbage collection. #629

Just a heads up if any one is using nodejs. The board will dip in brightness when the gc does a full mark sweep! this can be minimized by tweaking the gc memory params / forcing a manual gc when convenient for you (ideally when display blank or low brightness)

You might be able to mitigate some by setting the FIXED_FRAME_MICROSECONDS in your case https://github.com/hzeller/rpi-rgb-led-matrix/blob/master/lib/Makefile#L105
