tdf#135427 Make pstoedit delegate letter placement to us
As pstoedit documents itself, its wmf/emf driver uses a very approximate
interletter spacing, making the text look really awful. But it provides a
-nfw option that delegates the letter placement to the emf reader, and we
happen to be doing a proper job, thus getting a proper vectorized output.
This is not a concern on Windows (and the option is ignored there). The
option is available since version 3.40 (~2005). So we can just always pass
it on.
