gif from png sequence for twitter

	# Let's say an animation has frames {1,2,3,4}.png and is 24fps.
	# To make it loop nicely on twitter, we want something like:
	#
	# 1 1 2 2 3 3 4
	#
	# at 48fps. The below command, using a bunch of hacks, will
	# take a PNG sequence and create a gif with the above sequence.

	# Note that 2.0833333... is 1/48, e.g., 48fps.
