I've now updated on a machine that actually runs 'xscreensaver'.  The
problem display hacks that claimed "no image loading support" and/or
previously dumped core no-longer do.

A few of the display hacks that expect to load images still don't actually
do.  Instead, they only show the grey checkerboard "canvas".  They should
at least use the "xscreensaver" logo image if they can't load anything
else.

Still failing to load images:

  AntSpotlight
  Apple2
  BlitSpin
  Bumps
  Carousel
  DecayScreen
  Distort
  FlipScreen3D
  GFlux
  Gleidescope
  GLSlideshow
  MirrorBlob
  Photopile
  Ripples
  RotZoomer
  SlideScreen
  Spotlight
  Tessellimage
  Twang
  XAnalogTV
  Zoom

A clue is that the only core file left now is "xscreensaver-get.core"
which I believe is related to image loading.  It's not clear which of
the "/usr/pkg/bin/xscreensaver-getimage*" executables this matches, if
any.

Sure enough, the timestamp on the core file coincides with the time the
most recent of the above display hacks to be run (checking via
xscreensaver-demo).

If the display hack has a specific (set of) image(s), it loads fine.
If it expects a user-set image source (directory, screen-grab, video
frame, default xscreensaver logo image) then whatever produces that core
file dumps core.
