  printing on lp based systems like RedHat Linux 7.
* Added the posiibility to convert to PostScript without even touching
  the X11 environment.

  As most images in rtf files are metafiles this solves problems with the
  more complicated ones.

* Preparations for multi column layout.
* Preparations for 'Undo'
