Bug#324172: Xpdf 3.01 resize/redraw bug

[Derek B. Noonburg]

Once again, I'm sending email out to everyone who has contacted me
regarding the resize/redraw bug in Xpdf 3.01.

Thanks to Michael Rogers, I have a potential fix -- see the attached
patch file.  I would appreciate it if you would all try this out, and
let me know if it fixes the problem for you.
