-Note: unlike `xlock', xscreensaver has a client-server model: the
-`xscreensaver' process is a daemon that runs in the background; it is
-controlled by the foreground `xscreensaver-demo' program.

xscreensaver has an extensive manual -- please read it!
============
Along with the xscreensaver daemon itself, this package also includes

============
+Changes since 4.09: * New hacks, `cloudlife' and `klein'.
+ * Added Apple ][+, HPUX, and OS/390 sessions to BSOD.
+ * Added some Matrix Reloaded text to `xmatrix'.
+ * Updates to `webcollage', `eruption', `jigglypuff',
+ `metaballs', and `endgame'.
+ * Completely ignore the `memoryLimit' setting now.
+Changes since 4.08: * New hacks, `flyingtoasters', `bouncingcow',
+ `jigglypuff', and `glslideshow'.
+ * More models in `engine'.
+ * Rewrote `xscreensaver-getimage' to remove reliance on
+ external image loaders (xv, chbg, xloadimage, etc.)
+ and to reduce flicker when loading files.
+ * Made `gflux' and `flipscreen3d' be mouse-spinnable.
+Changes since 4.07: * New hacks, `atunnels' and `piecewise'.
+ * Physics improvement in `fluidballs'.
+ * Various fixes for XDarwin systems (X11 on MacOS X.)
+ * Added -clock option to `barcode'.
+ * Minor fixes to `endgame', `flurry', `flipscreen3d',
+ and `gflux'.
+Changes since 4.06: * New hacks, `flurry', `metaballs', `eruption',
+ `popsquares', and `barcode'.
+ * Minor updates to `maze' for high density mazes.
+ * Added double buffering to `fluidballs' and `whirlygig'.
+ * Bug fixes for running xscreensaver to a remote XFree86
+ display (which nobody would ever do...)
+ * Updated `webcollage' (faster Alta Vista searching.)
+ * Updated `glplanet' so the sun sets in the west.
+ * Updated `sproingies' with smooth, unsegmented surfaces.
+ * Fixed Perl version-sensitivity in
+ `xscreensaver-getimage-file'.
+ * Fixed GTK2 scrolling bug in `xscreensaver-demo'.
+Changes since 4.05: * New hack, `glblur' (disabled by default, since it
+ requires fast OpenGL texture support.)
+ * New hack, `halftone'.
+ * Updates to `endgame', `queens', `bumps', `glplanet',
+ `engine', and `circuit'.
+ * New version of `menger' that uses far fewer polygons.
+ * Fixed minor bug in `critical' that could cause some
+ bogus X servers to crash.
+ * Better labels in `molecule': the labels now appear to
+ be attached to the atoms, instead of floating in front
+ of the whole scene.
+ * Fixed bug that could rarely cause GL hacks to fail to
+ double-buffer (causing intermittent flickering.)
+ * Fixed a relative-URL-parsing bug in `webcollage'.
+ * Fixed a bug that (sometimes) caused the window manager
+ close box to kill `xscreensaver-demo' with a crash
+ instead of a graceful exit.
+ * Updated xscreensaver.pam to the Red Hat 7.3 way.
+ * More Gnome2-related configure crap.
+ * Updated to latest `config.guess' and `config.sub'.
+ * Fixed occasional core dump in `distort'.
+ * Added a Linux fsck failure and kernel panic to `bsod'.
+ * Added MacOS X kernel panic to `bsod'.
+ * Fixed a bug in `bsod' (all bsod bugs are ironic.)
+ * Fixed a bug that caused `xscreensaver-gl-helper' to
+ print a nonsense visual ID with some versions of
+ `printf': this could cause GL programs to display
+ incorrectly (e.g., flickery.)
+Changes since 4.04: * More `configure' tweaks to try and get things working
+ on systems that both Gtk 1.x and 2.x installed.
+ * New hack, `endgame'.
+ * Minor updates to `gltext'.
+Changes since 4.03: * Support for GTK 2.x / GNOME 2.x.
+ * The `configure' script will now use `pkg-config' if
+ you have it, in preference to `gtk-config', etc.
+ * New hacks, `lavalite', `queens', and `anemone'.
+ * Minor updates to `spheremonics', `gltext', `xmatrix'.
+ * You can use the mouse to manually spin most of the GL
+ hacks now (when they are displaying in a window.)
+ * Fixed a bug in `webcollage' (due to recent Alta Vista
+ url changes) that was causing it to try and load
+ incorrect image URLs.
+ * Made `xscreensaver-getimage' use gdk_pixbuf if it is
+ available: this means that those hacks that load images
+ will no longer rely on "xv", "xloadimage", etc. This
+ will close a race condition that could sometimes cause
+ your desktop background to be changed; and also makes
+ it possible for those programs to operate on image
+ files when running in windowed mode.
+ * `webcollage' can now be used in conjunction with
+ `driftnet' to display images snooped from your local
+ ethernet instead of obtained from search engines.
+ * Added man pages for all the hacks that didn't have
+ them.
+Changes since 4.02: * New hack, `spheremonics'.
+ * Minor updates to `webcollage', `cage', `moebius',
+ `morph3d', `boxed', `circuit', and `helix'.
+ * `pulsar' and `extrusion' can now load texture JPEGs.
+ * `rubik' now does non-square cubes.
+ * `fluidballs' now does various sizes of balls.
+ * `menger' and `sierpinski3d' now also show polygon
+ counts in -fps mode.
+ * `molecule' displays real subscripts in the formulae.
+ * GTK internationalization/localization support.
+ * Better detection of the various versions of libxml.
+ * Upgraded to autoconf 2.53 (from 2.13.)
+Changes since 4.01: * Plugged a few minor leaks in `xscreensaver' and
+ `xscreensaver-demo'.
+ * New hacks, `cubenetic' and `fluidballs'.
+ * Sped up `pipes'.
+ * Fixed sphere projection error in `glplanet'; installed
+ a better image of earth.
+ * Added Win2K and MacOS 1 crashes to `bsod'.
+ * Put back previous (better) version of `forest' that
+ was accidentially downgraded in the last release.
+ * New version of `bumps'.
+ * Made FPS computation in GL hacks more efficient: it
+ will influence the results less, thus resulting in
+ higher (but more accurate) reported frame rates.
+Changes since 4.00: * New hacks: `twang', `glsnake', `boxed', `sballs',
+ and `glforestfire'.
+ * New hacks `apollonian', `euler2d', `juggle',
+ `polyominoes' and `thornbird', from xlockmore.
+ * Merged recent xlockmore changes into `ant', `braid',
+ `demon', `discrete', `drift', `fadeplot', `forest',
+ `grav', `hopalong', `ifs', `laser', `lightning',
+ `lisa', `lissie', `loop', `mountain', `penrose',
+ `rotor', `sierpinski', `slip', `sphere', `spiral',
+ `strange', and `vines'.
+ * Fixed the `gltext' bug that sometimes caused
+ horizontal lines to vanish again. This time for sure.
+ * Sped up `webcollage' by adding a C helper program to
+ replace the PPM pipeline. It also pastes images
+ semi-transparently now.
+ * Added support for the gdk_pixbuf library: if this lib
+ is available, then `blitspin', `xflame', and `flag'
+ can load GIF, JPEG, and PNG images in addition to XPM
+ and XBM.
+ * Fixed a rare race condition where the desktop-grabbing
+ hacks could sometimes leave the screen wedged, if the
+ user moved the mouse exactly when they were grabbing
+ the screen image (it would un-wedge the next time the
+ saver timed out or was activated.)
+ * Fixed incorrect colors in the screen-grabbing GL hacks
+ (`gflux' and `flipscreen3d'.)
+ * Made SIGHUP restart the daemon process (though using
+ `xscreensaver-command -restart' is still the preferred
+ way.)
+ * Tweaks to `xspirograph'.
+ * Minor configure and portability tweaks.
+Changes since 3.34: * Redesigned `xscreensaver-demo' GUI: it now includes
+ small-preview and per-hack configuration dialogs.
+ * Added three new modes of operation: `One Screen Saver',
+ `Blank Screen', and `Don't Blank' (in addition to the
+ historical `Random Screen Saver').
+ * Configure now defaults to installing the hacks in
+ <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.
+ (Most distros already did it this way.)
+ * New GL hacks, `menger', `engine', `flipscreen3d'.
+ * Made `sierpinski3d' be more colorful.
+ * New versions of `xmatrix' and `nerverot'.
+ * Fixed a bug in `starwars' that made the font be drawn
+ with thin lines in -root mode.
+ * Fixed a bad colormap bug in `crystal' that could make
+ *subsequent* hacks malfunction!
+ * Made `gflux' able to grab screen images (`-mode grab').
+ * Updated `webcollage' for recent search engine changes.
+ * Removed most command-line options to `xscreensaver':
+ just edit the ~/.xscreensaver file instead.
+ * Improved behavior on multi-screen and Xinerama systems:
+ the mouse now stays on the screen where the user left
+ it, and the password and splash dialogs always appear
+ on the screen that has the mouse.
+ * Made the splash dialog use more Gtk-like colors;
+ made it have only two buttons, "Settings" and "Help".
+ * Made `sonar' understand `.ssh/known_hosts2' format
+ files, and be better about stripping out illegal
+ addresses.
Changes since 3.33: * Turned `memoryLimit' off by default, sigh. Apparently
some versions of the GL libraries (appear to) allocate
hundreds of megs for every GL program, so `memoryLimit'
* New GL hack, `circuit'.
* Added `fuzz' mode to `decayscreen'.
* New version of `whirlygig'.
- * Added links to `glplanet' and `sphereEversion'.
+ * Added links to `xplanet' and `sphereEversion'.
* Fixed rare race condition that could make `sonar' hang.
* Fixed potential crash in `speedmine'.
* Made `xscreensaver-demo' not crash when imageDirectory
is no longer needed.
* New versions of `rotzoomer' and `nerverot'.
* Fixed an OSF/1 compilation problem in `molecule'.
-Changes since 3.29: * New hacks, `molecule' `dangerball', and `rotzoomer'.
+Changes since 3.29: * New hacks, `molecule', `dangerball', and `rotzoomer'.
* New version of `gflux'.
* Made `gltext' able to display the current time.
* Fixed a floating-point-precision problem in `gltext'

* Added `maze' hack.
* Added `norotate' option to `rocks' hack.
+Changes since 1.4: * Works when run from XDM before anyone logs in.
+ * Sped up `imsmap'.
+ * Can use `xv' as a slideshow without using up colormap
+ entries while the screen is not blanked.
+ * Fixed a BadDrawable error in non-XIdle mode.
+ * Added `blitspin' and `imsmap'.
+Changes since 1.0: * Current list of included hacks is now: qix, helix,
+ rorschach, attraction, greynetic, rocks, pyro,
+ hopalong, and noseguy.
