  Thanks to all who helped.  I do have one last problem that I must ask:
any suggestions for current code workarounds?  My current thought is to
always send the aspect ratio hint, regardless of fullscreen state, and
never send it if the wm is metacity.  Should I use _NET_WM_NAME to check
for metacity?  Is there a proper way to work-around older versions of a
WM?  When not using _NET_WM_STATE_FULLSCREEN, I use override_redirect
for my fullscreen mode otherwise, and afaik this means that the hints
won't matter.

  The idea is that most window managers which support
_NET_WM_STATE_FULLSCREEN ignore the hint, except metacity, and by next
year or so fixed versions will be available generally and so I'll enable
the hint for metacity.

  Havoc, does this sound reasonable?
