phillips@cs.ubc.ca (George Phillips) (09/18/90)
Here is the official patch #1 for igif.
The patch contains a couple of trivial changes to make igif compile
on IBM RS6000 machines. There is also a little fix to make it work
better on GT series machines. A major stupidity in the event
loop has been fixed (yes, I know better than to busy wait, I just
slipped up), so you really should apply this patch.
You can apply this patch by saying "patch < patchfile". The changes
are small so if you don't have patch it's no big deal to do them by
hand. Or you can just grab the fully patched source from cs.ubc.ca.
Thanks can go to Paul Haeberli and karlton@sgi.com for the GT fix
and karlton@sgi.com for the event loop fix.

Dither should be done after enlarging the image. It isn't so using \-d
and \-2 may give a poor result.

+ The \-f flag has no affect on RS6000 systems.

+ The pop-up menu is not very nice on an RS6000 system, but
