Eye texture helper image

I am playing with texture painting for G9.

I noticed that regarding the eyes I don't really see which area of the texture is which area on the geometry.

So I made simple helper image.

It is a png with transparent background. If you put it on top of your eye texture in your image editor, you can see what area of the texture goes where on the eye.

In case anybody has a use for it, it is attached.
