I keep running into this problem and I can't figure out where it comes from. The performance between graphics and bitmapdata is just too big.
 
	These fiddles are based off the starfield examples

	I've only added the game.time.fps to the fiddles.
 
	https://jsfiddle.net/rf2gcfnz/ - with texture I get 34-36 fps,
 
	https://jsfiddle.net/7a87eL9n/ - with bitmapdata i get 58-60 fps.
 
	Why is that? I believe that texture and graphics should be faster then the bmd, as drawing to bmd involves another step as drawing to bmd and then to the screen. What am I missing?
