Work at 3ds support and backend upgrades

- 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
