I found a good reason for storing the PS in a string first:
we have to process all of the figure before we write the PostScript
prologue.  Otherwise there is no good way to know which fonts
to include in the PostScript file :-(
I reverted my change for now, we are back to storing the PostScript
data temporarily in a string.

All the best,
Jochen
