Subject: diagnostic PS hack

Here's a PostScript hack for diagnosing complex documents. If you drop
it into any environment, anywhere, it figures out the current
coordinate system and prints a grid overlaying the page that labels the
page in the current coordinate system. I've been meaning to integrate
it with an errorhandler so that it can be automatically invoked if
something goes wrong. 

I call this file PScoords.ps. I don't have a %! on it because I usually
use it by inserting it into a file that didn't print and then printing
the file a second time.
