*
* We should have thought of storing those in the data . . .
* It is possible to extend the data structure by putting additional values
* in places that are inaccessible by ordinary enumeration of the item tree .
* For example , additional integers could be stored at the beginning or
* end of the key strings ; this could be indicated by a minor version number ,
* and the data swapping would have to know about these values .
*
* The data structure does not forbid keys to be shared , so we must swap
* all keys once instead of each key when it is referenced .
*
* These swapping functions assume that a resource bundle always has a length
* that is a multiple of 4 bytes .
* Currently , this is trivially true because genrb writes bundle tree leaves
* physically first , before their branches , so that the root table with its
