Anisotropic filtering and Anti-aliasing settings do not seem to work

[matejdro]

• When enabling, Anisotrophic filtering, game will freeze for couple of seconds (as it does on the desktop OptiFine, no issues here), but when it comes back, AF will still be at 1x.
• When enabling Anti-aliasing, changing the slider will not do anything. Even if I move slider all the way to the right, it will still says that AA is not disabled.
