   Anyone know:

   How does one scale a view so that it will fit width-wise on a printed page?

   Using printPSCode, if my View object is too wide it gets clipped off on 
   the right.

This is a fun one!  What you want to do is adjust the pagination in
the application's printinfo.  Here's what I do in the printing
section of Stuart:

  PrintInfo *pi=[NXApp printInfo];
...
  [pi setHorizPagination:NX_FITPAGINATION];
  [pi setVertPagination:NX_AUTOPAGINATION];
  [pi setHorizCentered:YES];
  [pi setVertCentered:NO];

NX_FITPAGINATION tells it to scale the image as needed to fit.
This will only occur if the image is larger than the page.
NX_AUTOPAGINATION tells is to split into pages (that's the
default, I think).  I center it horizontally, in case it's
not wide enough to invoke the scaling.  I don't center
vertically, so it will go to the top of the page if it's too
short for the page.

I implemented this as part of the printPSCode: method that's
to do the printing.  Basically, you could do all this stuff
followed by 'return [super printPSCode:sender];', I believe.
