[texhax] Reverse page numbering (begin with the last page number and end with 0)

[Othmane Benkirane]

Sorry, in fact I want the result of \pageref{LastPage} - \thepage to be written in the headers (it should begin with \pageref{LastPage} - 1 and should finish with 0). My mistake.

Regards,
Othmane Benkirane.
