That is what I was trying to say. Jeff: If you think that "Well,
since the PDF back-end can't be fixed any time soon, we might
just as well drop it", I prefer a partial PDF back-end to none at

Indeed. I see two more or less seperate projects:

1) Make Lout generate nothing but basic graphical objects. Add
   layer which takes these objects and generates output for the
   target back-end.
2) Move some of Postscript's power into Lout.

The latter project has (at least) 3 solutions:

1) Provide hooks for external modules. External modules could
   define new Lout functions. Statically linked into Lout at
   first, support loading on the fly later.
2) Make Lout a full-blown programming language.
3) Use current external program support. Has some security issues
   which need to be addressed.

(I purposely glossed over some problems here. I'll address them later
if necessary.)

This nice list should really be put up on the web site. Did I
mention that the source tree doesn't have a TODO file? After all,
if you are short on time, use every means available to draw in
other people's resources. Leverage the potential of Open Source.

Wish I had the time. Also, the strange source naming convention
has held me off from looking at the code when I _did_ have a
little time.
