Thanks for your contribution! I appreciate how small and concise it is! However, can I get a bit more explanation of this? What is the problem being solved. Why does rotation need to be done with shader rather than rotation of just the normal map image? Can I get a sample to run of it working or adding to the examples? |

Sure, I've added rotation to the normal map example. I had to add a background rectangle to hide rendering artifacts left over from light world. You can remove this line to recreate them if you'd like. |

add new shader to rotate normal map vectors in world coordinates to correctly align with the rotation of the sprite being drawn
