Subject: [PATCH] Fix if you change from normal to normalfast render mode, then
 move to inside a block with fog of some sort like lava/water, then resize the
 game window, and you are using Direct3D9, your game crashes. (Thanks fam0r)

So for the 87th time, I have permanently fixed the issue of leaking GFX resources for good.
