34: Modified:
35: 04May88 Leo Final event types and record
36: 22Aug88 Leo Change short -> int for window, add reserved
37: 26May90 Ted Added NX_UNDIMMASK to correct triggering of UndoAutoDim
38: 12Dec91 Mike Brought into sync with dpsclient/event.h, and fixed
39: the #ifndef interlock with dpsclient/event.h that was
40: broken during the Great Header Revision.
41:
42: The PostScript version of this file differs from the
