I've learned a lot about what could be done in which way from all the examples i recieved. Boguslaw Jackowski sent me his hatching package which does exactly what i need and more. It's great and i can only recommend it for this purpose.

Cheers Laurent S. The readme file: (English!) | The file HATCHING.MP contains a set of METAPOST macros for | hatching interior of closed paths. | | made in BOP s.c. | e-mail: B.Jackowski@gust.org.pl | public domain software | (no copyrights, copylefts, copyups, copydowns, or whatsoever) | | 21.09.2000 -- ver 0.11 (pre-release) | | The basic macro, hatchfill, works very much like the standard | fill command. The general form of the hatchfill command call is | as follows: | | hatchfill path_expression withcolor c1 withcolor c2 ... | | The trick is that for hatching special ``colors'' are used, | namely, if bluepart(c)<0, the colour c is interpreted as hatching | data: | | | hatching angle redpart(c) | distance between lines greenpart(c) | thickness of lines -bluepart(c) | | Dashing and colouring of the hatch pattern can be accomplished by | using hatchoptions command (cf. drawoptions in plain.mp). | Actually, an arbitrary pattern can be used instead of straight | lines: it suffices to redefine the macro draw_hatched_band (cf. | htchuse.mp, figure 103), although one should be aware that | METAPOST memory can be easily overloaded and that the resulting | EPS files are usually annoyingly large. | | The examples of usage can be found in htchuse.mp; for | convenience, a trivial TeX file for typesetting the figures, | htchuse_.tex, is included.

And how would I determine the size of the text and whether my replacement text would change the layout? [sorry for getting Graphviz specific here. I am trying to make my point clear.] There are two main issues. First is that edge labels can only contain text. Node labels can be of a "record" type which adds some basic table support. Node shapes can be selected from a variety of different geometric shapes. Or node labels can be Postscript files (for the Postscript and SVG drivers anyway). I thought about adding support for edge labels to be arbitrary Postscript files. That way I could use user defined node/edge attributes containing (La)TeX code. A preprocessor mechanism could render the graphics and include the resulting Postscript files as node/edge labels accordingly. For nodes this worked in a proof-of-concept study I came up with. I was the preprocessor, BTW ;-) > It doesn't seem simple. Why not stick to a specialized tool > and enhance it? First of all Graphviz' code base is, well, mature ;-) One of the developers I discussed that issue with agreed that it is quite messy. Particularly the Postscript file handling is inefficient and full of bugs. Fixing that is a task that would probably be not much easier than implementing the layout features in Metapost. And in the end I still haven't solved the problem that I might want to have more than just a graph in my picture. Post-editing is a manual process since other objects don't have any knowledge about the graph objects. Each time I make a minor change to the graph, all the code I added might be worthless. Anyway, I was just curious if anybody had the same idea.
