Mmmh, macros defined outside? And how preview-latex can help in this way? > 2) It does the cropping for you (at least when using > pdflatex, I > don't remember for the other backends).

Perhaps they know better. I'll investigate that. Maybe it's faster in some way. Enrico: I'm also trying to understand if there's a way to make GhostScript ignore errors so we don't have to make a lot of files with "dvips -i" and a GS call for each one. On the #ghostscript IRC channel on freenode I've been told that making a single call on a PostScript referencing all the other files would be a great improvement, because each GhostScript call is very heavy by itself, and all the file parsing and rendering is made very quickly. This is what they say! Otherwise they suggested to put an errorhandler inside a single big PostScript which would allow us to ignore errors and go on until the next page. venom00
