Texture Mapping extension

[Tim Gould]

I was being a little extreme, but you would have to design the tile twice to fall back OK. Which may not be super difficult depending on how crude the fallback was.

Having the part external of the main library would allow the designer not to worry about making a crude fallback part (or to make a really, really crude one). Having them internal would require some balance of quality of fallback.

EDIT: Having given it a little more thought you could use very low-res versions of the texture to automatically make a fallback part so I take back that issue.
