Upgrade to 5.13:

* Optionally enabled full-scene OpenGL antialiasing. Set the resource
  *multiSample to true if doing so doesn't kill performance with your
  video hardware.
* New version of glhanoi.
* Image-loading hacks that display the file name now also display the
  sub-directory (xscreensaver-getimage now returns relative paths under
  imageDirectory).
* Passwords that contain UTF-8 non-Latin1 chars are now typeable.
* Numerous minor stability fixes.

For the port, remove patch incorporated by the author, and now-obsolete
