Cutouts are broken

Used to be able to see through gaps in leaves, and through glass blocks. Something recently broke that. I vaguely recall messing with alternative shaders so users with slow GPUs can disable haze, so maybe that had something to do with it.

Yep, was related to shaders. Forgot I was experimenting with another fragment shader, and it happened to be one that didn't discard pixels with an alpha value less that 0.5.
