MaybeInstallFallbackCargoLabel()

static void MaybeInstallFallbackCargoLabel ( uint  id, uint  last, CargoLabel  label  )

static

Install cargo label in a fallback cargo list, if a NewGRF-defined cargo list is not present.

This allows this NewGRF to use its self-defined cargo types without needing an explicit translation table.

Parameters

id	ID of the cargo.
last	ID of the last cargo being set up.
label	Label to install.
