*
* Walk an enhanced metafile, calling a user-specified function _EnhMetaFunc_

* when _EnhMetaFunc_ returns FALSE.
*
*
* RETURNS
* TRUE if every record is used, FALSE if any invocation of _EnhMetaFunc_
* returns FALSE.
*
* BUGS
* Ignores rect.
*
* NOTES
* This function behaves differently in Win9x and WinNT.
*
* In WinNT, the DC's world transform is updated as the EMF changes
* the Window/Viewport Extent and Origin or its world transform.
* The actual Window/Viewport Extent and Origin are left untouched.
*
* In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
* 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
* TLS.
