 *  Based on CView::OnFilePrint() - but with one bug fixed (at least originally). That code was buggy when used in an OCX cuz there
 *  is no doc and no frame window (perhaps I could have created one - but I wasn't sure what other bugs/problems that might create).
 *
 *      Then - when I tried to compile that code here - there were all sorts of things that wouldn't compile. So I had to make a bunch of
 *  OTHER changes due to the fact that I don't include all the private MFC headers here. And as long as I was making such bug changes - I threw away
 *  a bunch of detritus as well.
