- Track textures (not sure if this is done tbh) - Add lithium formatters and move TextureID, TextureFormat and TextureFilter to lithium - Only include gl-helper if any glDriver is included - Add Li::Rect for UV stuff - Add Li::Texture as Info holder (still thinking of making them to ptrs - Add Check if textures are still loaded on exit
