Screenshot on medium setting

In the game Heroes of Newerth, turning the setting "Shader Quality" to medium
or high results in corrupt rendering of water.

This seems to be a regression from the glsl2 merge, but it seems fine on
llvmpipe, so I'm guessing the bug is specific to r300g.

I _think_ it's possible to reproduce this bug without buying the game, by only
registering and then either starting a practice game or running the tutorial.
If not, I'll see about getting some trial invites. 

The rest of the effects in the game seems to be working fine.
