- Renamed texture setting function (setTexture) in most video drivers to setActiveTexture and made sure it has the same signature. This avoids confusion with similarly named methods in other classes (Such as SMaterial) and the consolidated method signature will hopefully help future plans for better abstracting texture usage across all drivers.
