#29 Minor issues with printed ORM diagrams

A couple of minor annoyances when printing ORM diagrams. I
print to the "MS Publisher Imagesetter" driver to get a Postscript
file which I then distill to PDF. These can be lifted nicely into
Keynote (Macintosh presentation software), and thankfully appear
without a white background.

The grey shadow around items that appear on two diagrams is
too dense, so that overlapping text is hard to read.

The objects are all too small and I can't see how to ask to
enlarge them, for example to fill the page, or by a %age etc...
Keynote can deal with that, but paper doesn't stretch as well :-)
