I think this should be 'fixed' by supporting conditional NP2 textures
only when texture_rectangle is supported and get rid of other
situations where we scale coordinates.

- -> Fake NP2 cube textures: I don't see how this can possibly work.
We're merely length-scaling a directional vector.

- -> GPUs that don't support ARB_texture_rectangle: Unfortunately I
don't have one of those, but not advertising NP2_CONDITIONAL on those
should be legitimate.

- -> Fallback for P8 textures and EXT_paletted_textures: Problematic
because I can't test this. Not sure if the code even works...
