* Pure text documents should better be translated into text flow instead
  of a mess of text objects (as does pstohtml).
* Non standard fonts (e.g. TeX's bitmap fonts ) are translated into Courier.
* only limited support for special character encodings.
* No support for bitmap images
* Framemaker addes linewidth also to linelength. So if the linewidth is not very
  small relative to the linelength the generated line will look very different 
  from the original one.

  This we want:
     -----------
     |         |
     *   *     *
     |         |
     -----------

  This we get:
  -----------------
  |               |
  |  *   *     *  |
  |               |
  -----------------
  This could be corrected by readjusting the points (substract/add line width)

* The GNUPlot backend is very limited, e.g., doesn't support text at all.
* There are some problems in the OS2 meta file output. The metafile viewer fails in some
  cases, although drawing directly to the screen works ok. If you have an idea what's going
  wrong here, please contact Christoph Jaeschke <jaeschke@imbe05.imbe.uni-bremen.de> and tell
  him how to solve the problem.
* The .wmf files generated by the WMF backend are not "placeable" meta files.
  This will be fixed soon.
