Time.prevTime is a new property that contains the raw value of the game timer from the previous update.
Timer.timeCap has been changed from `1000` to `1 / 60 * 1000` to bring it in line with Time.timeCap.
Merged latest Pixi dev build.
Updated the grunt manifests.
Removed old WebGL UV calls.
Happily removed the IE11 WebGL lock as Pixi now fully supports it :)
readme updates.
Cute little new shader.
