I don't think that your exegesis can be supported by the text. The range
is 0 to 16777215 for each FontType, separately. That is, fonts with different
FontType need not have different UniqueID in order for font cache integrity
to be maintained.

In my reading, the range is 0 to 16777215 and this fact is documented in
the section you just quoted.
