  Revision 1.12  1996/12/18 18:52:01  wenger
  Devise requests Tasvir not to use subwindows for its images; sizing of
  Tasvir images now basically works like a RectX, except that the aspect
  ratio is fixed by the image itself; fixed a bug in action of +/- keys
  for RectX shapes; Devise won't request Tasvir images smaller than two
  pixels (causes error in Tasvir).

  Revision 1.11  1996/08/23 16:55:32  wenger
  First version that allows the use of Dali to display images (more work
  needs to be done on this); changed DevStatus to a class to make it work
  better; various minor bug fixes.

  Revision 1.10  1996/08/05 19:51:36  wenger
  Fixed compile errors caused by some of Kevin's recent changes; changed
  the attrproj stuff to make a .a file instead of a .o; added some more
  TData file writing stuff; misc. cleanup.

  Revision 1.9  1996/08/05 17:28:58  beyer
  Added is_safe() which checks to see if a double is safe value (ie, not
  NaN or Infinity).  Made SetVisualFilter check the new filter for safety.

  Revision 1.8  1996/08/04 23:33:16  beyer
  Added #define for NULL

  Revision 1.7  1996/07/31 19:34:30  wenger
  Added AttrProj member functions for reading entire records (no projection).

  Revision 1.6  1996/07/13 04:59:31  jussi
  Added conditional for Linux.

  Revision 1.5  1996/06/21 19:29:11  jussi
  Cleaned up file and replaced MinMax class with simpler MIN/MAX macros.

  Revision 1.4  1996/05/20 18:44:40  jussi
  Replaced PENTIUM flag with SOLARIS.

  Revision 1.3  1996/04/15 19:32:05  wenger
  Consolidated the two (nearly identical) functions for
  reading/parsing physical schema, and cleaned up the
  ParseCat.c module quite a bit.  As part of this, I added
  a new enum DevStatus (StatusOk, StatusFailed, etc.).

  Revision 1.2  1995/09/05 21:12:39  jussi
  Added/update CVS header.
