I added support for drawing onto printer device contexts. This means
that you have printer support -- a user gets a printer dialog etc. and
can print, while the haskell code just draws to a DC -- either the
screen or a printer. On windows, I can simply select a postscript 
printer and print to a file to get postscript output.

However, I have not added specific support for getting postscript
output directly, even though I can vagelue remember that wxWidgets
has such support -- if I find time, I'll look into it, but I am
hoping that also on unix, one can emulate this behaviour by selecting
a postscript printer and printing to file.
