This is a list of patches applied to ivtools over the course of
ivtools-0.4 development, which ran from approximately September 1994
until October 1995.

ivtools originated with a 0.3 version designation in January 1994,
since this was approximately the third time our team had started from
scratch building a value-added library version of idraw.  From January
1994 until September 1994 the structure of the libraries of ivtools
was determined, and the first versions of OverlayUnidraw,
FrameUnidraw, and GraphUnidraw were created, along with their sample
programs: idraw, ov-idraw (now drawtool), frame-idraw (now flipbook),
and graph-idraw (now graphdraw).
