[pstricks] [Fwd: Re: [VTeX] fancybox and pstricks]

Denis, what do you say to Michaels suggestion for
pstricks.con?

The solution with \immediate\special{header=pstricks.pro}
worked well for me.

This is a nice one.

Here is what is happening:

tx at Dict is defined in pstricks.pro; and the reason why it seems to be
undefined is that pstricks.pro is loaded *after* fancybox executes.
Specifically, the headers are loaded "\AtBeginDvi" (see the pstricks.con
file); but fancybox outputs before the first "DVI" page is processed.

Notice that this is never a problem with multi-pass processing, like DVIPS,
or like VTeX in non-GeX  PostScript mode (-$s); it is a problem in a
single-pass processing (-ox2 -$s OR -ox2 -$p) where everything is processed
right away, and fancybox specials come first.

Now, a simple workaround is to force the header to be loaded; add to the doc
preamble
before fancybox code

\immediate\special{header=pstricks.pro}

You may also try to change pstricks.con to use \immediate\special in
\pstheader. This does work for your example, and __I think__ it may always
work (this kind of change needs to be tested on lots of pstricks examples.)
