If a Metafile's scaling is incompletely defined, there are some arbitrary values used.
This bug is just filed as regression because aoo 3.3 used the WMF part and Lo the EMF part!
Please use environment variable EMF_PLUS_DISABLE if you have further problems with EMF files.
This Patch also adds an (untested) TWIPS scaling, which was missing.
known issue: vertical text ratio still scaled differently than lineart.
