* BUGS

* NOTES
* This function behaves differently in Win9x and WinNT.

* updates the scaling itself but only just before a record that
* writes anything to the DC.
*
* I'm not sure where the data (enum_emh_data) is stored in either
* version. For this implementation, it is stored before the handle
* table, but it could be stored in the DC, in the EMF handle or in
