Snow cottage at (121.50, 126.50, 63.70). `load_OBJ` can't load it fully.

`load_OBJ` is not able to process face (`f`) lines that are in different
format. At the moment `load_OBJ` simply skips those lines. `load_OBJ`
also doesn't know how to process material lines, so
`snow_cottage_triangulated.obj` has been stripped of material
information.

All tests pass.
