The muscle of a real operating system makes a hack like "print preview"
look pretty puny.  
An even better answer would be to define a fifo for the purpose.  

If .dia/diarc defined a fifo and an external postscript displayer (say,
ggv), "print preview" would be simple to implement: fork a process to
write to the fifo, and launch the displayer.  Not very different from
defining helper applications in your favorite web browser.  Or the way
Bluefish uses a browswer, or the way....

Sadly, it seems ggv won't read from stdin.  If it could, dia could write
to stdout and skip the fifo.
