Created Leo 01Mar88
Modified:
04May88 Leo Final event types and record
22Aug88 Leo Change short -> int for window, add reserved
26May90 Ted Added NX_UNDIMMASK to correct triggering of UndoAutoDim
12Dec91 Mike Brought into sync with dpsclient/event.h, and fixed
the #ifndef interlock with dpsclient/event.h that was
broken during the Great Header Revision.
The PostScript version of this file differs from the
Window Kit version in that the coordinates here are
ints instead of floats.
