  11.  
  12.          <8>     5/15/95    RB        Adding CA_CATCH
  13.          <7>     4/18/95    SJF        Fix CAGetCanvas - note that the graphics
  14.                                                     System is preset to kODQuickDraw which is
  15.                                                     probably uncool!
  16.          <5>     4/07/95    RB        Fixed some ref counting errors
  17.  
  18.          <4>     3/30/95    RB        Added routine CAForceUpdate().  Used by the app
  19.                                                      to force the update of a region, for scrolling.
  20.                                                      
  21.          <3+>     2/28/95    SJF        Add debug stuff to API calls
  22.          <3>     2/13/95    SJF        Interim checkin to update project database
  23.          <2)    12/15/94    SJF        change somGetGlobalEnvironment to _gpProxyShell->GetGlobalEnvironment
  24.          <1>    12/12/94    SJF            Fix up after adding TCAProxyShell stuff...
  25.          <0>    10/30/94    GCA,DHN    All mods to make project compile with no
  26.                                      errors under OpenDoc b1 (with SOM).
