WindowRef.getWidth/getHeight and ItemStackRef.isEmpty/getMaxDamage
match methods of the classes they're mixed into, so the mixins can't
implement them explicitly. With Mojang's names, Window.getWidth is
also the framebuffer's width rather than the window's. They're now
getWindowWidth/getWindowHeight and isEmptyStack/getMaxItemDamage
(with getItemDamage to match).
