[Bug 38654] King's Bounty series: water rendering broken when anti-aliasing enabled

--- Comment #3 from Stefan Dösinger  ---
I suspect that the game mixes multisampled color buffers with regular depth
buffers, or vice versa. I suspect the correct thing to behave as if no depth
buffer is attached. Prior to 90d88968 we used an uninitialized depth buffer
with the correct properties, so GL rendered something. Now we set up an
incorrect FBO and GL refuses to do anything.

I ran into this with one of our tests but decided not to fix it until we have a
game that needs this. Looks like we have two already.
