In sprite.lua,Sprite.setBlendFunc,Sprite.clearBlendFunc,BlendFactor are set to nil,
the combination of blend mode is limited.
If all combination is available, we may make a simple mask effect like this

As I known, atilim set these to nil just to make the api simpler to use, but these apis may be available as a bonus.
