tdf#113624 EMF+ Add support for different units conversion
With previous implementation only Pixel unit was supported. Other units (eg. inch, milimeters, points, world) was treated as Pixel. With this patch the correct unit conversion was implemented to following records: - FontObject - PenObject - SetWorldTransform As a result records are properly scaled. Tested with DrawString record from: https://bugs.documentfoundation.org/attachment.cgi?id=140287 Change-Id: I77435ad8f1bbac08f298a03d91d0c7f1f1734e5c Reviewed-on: https://gerrit.libreoffice.org/52699 Tested-by: Jenkins <ci@libreoffice.org> Reviewed-by: Bartosz Kosiorek <gang65@poczta.onet.pl>
