 Dear all,
 I've just updated a patch that simply adds two new converters to LyX:

 This basically allow us to have an equation editor-like mode in

I like the goal, but making eps a document format will cause unwanted 
entries to show up in export and view menus. This shows again a limitation 
of our converter code, where you cannot easily suppress unwanted edges in 
the conversion graph. I believe however that it should work if you would 
instead use a new EPS (cropped) format similar to the new pdf format.

  We can easily provide an 'equation editor' mode in LyX. For this we can

  This would allow for LyX to act as a generator for includable graphics
  (equations, commented graphics, etc). It would (partially) address a long-
