Is anyone else having trouble with the new canvas blendmodes on IOS7 with pixi?   Specifically I'm having an issue with SATURATION.  I'm overlaying a black tinted sprite set to SATURATION blendmode expecting it to desaturate the underlying sprite.    Here's a screen capture of what I'm seeing. Top image is ios7 bottom image is chrome on mavericks.    I filed an issue on github here: https://github.com/GoodBoyDigital/pixi.js/issues/708
