A per pixel lighting feature request

Hey Niko, I would like to make a feature request, can you make it so the per pixel lighting does'nt require tangents?.
Thanks

I don't mean to sound mean, but you should read up on normal mapping (and per pixel lighting in general) to understand why tangents are useful.

not only usefull but necessary.

Really?, I'll have to check that out. But what about this shader?

that shader calculates the tangents and binormals by itself which makes it way slower.
