Notes:
- NME's HTML5 performance is still undergoing optimizations; it is DOM+canvas based instead of full-canvas, except when using Tilesheet.drawTiles which RunnerMark leverages.
- JS weight: 279Kb (dead-code removal), 196Kb (google closure "simple"), 53Kb (gzip -6)
- why "so heavy"? NME's HTML5 implementation is nearly the entire Flash runtime in JS!
