There are already the FreeByteOffsets and FreeByteCounts (288 and 289) tags
for keeping track of unused space. Nothing is specified about in which IFD
they belong, though (the first? the last? wherever you want, and use all of
them together?). The spec also says: "not recommended for general
interchange", probably partly because of this, and also because it's not
very nice to give someone a space-wasting file, I guess :-).
