Updated. btw Thanks for your contrib to AS3 Tweener. It is a great kit. I think performance tests and benchmarks can only improve performance so I see this as a good thing. I think that Jack did a good job getting his kit into the channels. He also highlighted where TweenLite might be useful where other tools with more overhread like Tweener’s special properties and other kits overhead can slow things down. It really is a by project decision but many times I need the bezier curves or tools from other kits but animation kits should be small and compact and extremely fast. I think this will help all kits for the better knowing there is a benchmark out there. It is a win for everyone if we focus on performance.
