Bugzilla Bug 219172

I have a Xinerama setup laid out with a laptop monitor and a larger external
monitor.  I noticed a strange behavior when xscreensaver-5.05 came out and I
emerged it.  It would run the screensaver on the top (external) but the desktop
was exposed on the bottom.  The mouse and keyboard were locked into the login,
so it didn't completely leave the desktop insecure, but it was still not
acceptable.

I found a bug and patch via bugs.debian.org:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=473681

I tested the patch in message #18.  It is a clear one-liner and resolved my
issue.

Reproducible: Always

Steps to Reproduce:
1.Xinerama flag set.
2.Two screens, a larger resolution on top and a smaller resolution on bottom.
3.xscreensaver-command -lock

Actual Results:  
Blanked top screen.

Expected Results:  
Blank both screens.

Applied into 5.05-r1, thanks.
