Make texture system compatible with Optifine

I know this is redundant and overly suggested, but we need this now. Some of us actually can barely have a good framerate without Optifine installed and it boosts our performance in ways that the regular game would not. I'm not asking to make a dependency or to support all the graphic features of it but please add some kind of compatibility with Optifine so that we can enjoy our game fast and with textures.
