Wouldn't be better to create a separated function like draw9SliceSprite()?

possibly, but then it would make sense to also have one for drawTiledSprite(), etc., idk if it's worth it.

I think it does. We reduce overhead in sprite drawing functions, what do you think @mflerackers?

[dragoncoder047]

i think it conflicts with the way sprites are defined, that is, the slice9 parameters are stored in the sprite metadata, so what would happen if you called draw9SliceSprite with a sprite with no slice9 metadata. Or vice versa
