   2) Ability to use the entire postscript character set in text objects
   (not just the bottom 128!).

3.0 idraw is meant to support such characters via the Meta key;
however, there is a bug that prevents this from working consistently.
Below is the patch:

*** /interviews/dist/3.0-beta/iv/src/lib/Unidraw/manips.c	Thu Apr  4 22:46:50 1991
--- src/lib/Unidraw/manips.c	Tue Apr 30 12:03:29 1991
***************
*** 608,614 ****
          case '\015':  if (_multiline) InsertCharacter('\n'); break;
          case '\033':  manipulating = false; break;
          default:
!             if (!iscntrl(c)) {
                  InsertCharacter(c);
              }
              break;
--- 608,614 ----
          case '\015':  if (_multiline) InsertCharacter('\n'); break;
          case '\033':  manipulating = false; break;
          default:
!             if (!iscntrl(c & 0x7f)) {
                  InsertCharacter(c);
              }
              break;

   7) Constrained move, like on the mac.  I.e. when you hold down the
   shift key during a move, you can move the object horizontally or
   vertically, but not both.  (Suggested by Gary Bradski I think.)

This works in 3.0 idraw exactly as you describe.
