inline

Todo.

Todo. Inverts the perspective texture mapping. Can be derived using some tedious algebra. NOTE: This one actually takes/needs the perspectively corrected lambda I think!

Todo: Probably move to a texturing file, internal/detail one, where we will also put the tex2d, mipmapping etc stuff?
