Note to Windows users:
I suspect this was Windows-related, or at least done by a Windows
coder. There are many places where subwindows are dirtied explicitly,
which is way inefficient in Xt or GTK+ coding. At least from the
XEmacs code I've looked at, it doesn't seem like Windows has a proper
notion of "widget", so you need to redraw stuff "by hand" all the
time.
I have tested this with a cygwin build on windows (./configure --with-msw
--without-x) and found that the display behaviour didn't change. There
were some glitches in a right side toolbar when I resized, but they
happened with and without the patch.
