fonst partially embedded in PDFs often do not contain an OS2 table.
Wine did not accept these fonts and uses another fonts as replacement
This leads often to completely unreadable documents as the glyp index does
not match the one of the choosen replacement font.

This patch accepts such fonts and inserts checks where wine assumed
that the OS2 table does exist.
