Bugzilla Bug 135210

accord/bumping to http://www.jwz.org/xscreensaver/changelog.html v5.0 is
released

<Changelog>
    *  Ported to MacOS X! (10.4.0 or newer)
    * API change: instead of providing a single screenhack() function that does
not return, screen savers using the screenhack.h framework must now provide
``init'' and ``draw one frame'' functions instead. All bundled savers have been
updated; third-party patches will need work.
    * All image-loading happens asynchronously.
    * xscreensaver-getimage-file caches the contents of the image directory for
a few hours, so consecutive runs won't have to re-list the whole directory
tree.
    * New hacks, topblock and glschool.
    * Removed xteevee (superceded by xanalogtv).
    * Added variable-sized puzzle pieces to jigsaw.
    * Changes to the defaults and command-line options of many hacks to make
the .xml files more consistent.
    * Reap zombies in glslideshow and carousel.
    * sonar works without setuid on OSX (dgram icmp).
    * xmatrix -mode pipe displays the text of a subprocess.
    * endgame has higher resolution chess-piece models.
    * webcollage takes a -directory option to get images from a local
directory.
    * The RPM spec file no longer auto-restarts xscreensaver when a new version
is installed. Restart it manually. 
</Changelog>

the api has changed so i don't know about 

gnome-extra/shermans-aquarium
kde-base/kdeartwork
kde-base/kdeartwork-kscreensaver
net-im/gaim
net-im/psi
x11-misc/rss-glx

kdeartwork doesn't have any problems interacting with new version, Psi seems to
work ok too. Third party screen savers will need to be ported by upstream.
Anyway: bumped :)
