/// Transform.js

	http://www.w3.org/TR/css3-transforms/#interpolation-of-transforms
	Four rules for interpolating transform lists:
		* If both lists are none, return nothing.
		* If one of the lists is none, create a equivalent identity list, continue to next rule.
		* If both lists have the same amount of arguments (having a common primitive), interpolate each pair of transform function and return computed value.
		* else in worst case, convert both lists to matrices and interpolate those, return computed value.
	
	To minimize GC, we have only one static object.
