tdf#127471 Detect&Correct EMF/WMF with wrong FontScale

Before correcting our EMF/WMF export to write the Windows-
specific data in the case of FontScaling, we wrote these
files with wrong FontScaling.
This change tries to detect and correct this at import, so
that newer versions of the office on all plattforms can
again load old, from us but not on Windows written EMF/WMF
files.
With this change we can read again all new and old EMF/WMF
files (see table in task, comment 80).
