Ninja-hack to make minecraft AO example working again after big deflipping.

Don't try this at home kids. Finally had to do it like this, alternative was just getting slowly insane (I spent lot of time on futile attempts to make it in the "right" way, it doesn't even show any texture with UNPACK_FLIP_Y_WEBGL toggled on).
