The hash value is used for looking up the hash table (after performing a
hash % table_size). size_t would be a better type since the hash table
object can't exceed size_t. Scaled fonts uses a pointer as a convenient
means of generating a hash value. But the hash value in general is not
intended to contain a pointer.
