Log Message:
Update to 4.16:
* New hacks, `polyhedra', `fuzzyflakes', `antinspect',
  and `providence'.
* Minor updates to `webcollage', `bsod', `endgame',
  `antspotlight', `xmatrix', and `glmatrix'.
* Added support for the RANDR (Resize and Rotate)
  extension to detect when the size of the desktop has
  been changed while xscreensaver is already running.
* Possibly-futile attempt to work around "rdesktop"
  focus/grab idiocy.
* Made `xscreensaver-getimage -file' still work even if
  imageDirectory is unset.
* Convert Latin1 to ASCII in `starwars' and `phosphor'
  (since the GLUT font only has ASCII glyphs.)
* Fixed randomization in `noof'.
* Added "GetViewPortIsFullOfLies" preference to work
  around longstanding XFree86 bug #421.
* Made `sonar' subnet pinging work properly on bigendian
  machines (e.g., PPC.)
