     * OpenGL blend function to something like SRC_ALPHA, SRC_ALPHA or ONE, ONE. The thing is... they're not very
     * Minecraft-y. I still maintain that part of wizardry's appeal is that it stays true to the game's pixelated charm,
     * rather than trying to make it something it's not. Still, the newer textures are much better than the defaults I
     * used to use.
