I belive you could do something hackish like this if you don't want to patch
for actual support. But you need to be a little more creative.
First I belive GetOutput is excuting a shell command, so you may just need
(GetOutput {echo $PANEL_FONT} 1 -1)
this should work for the enviorment variables but not infostore (I'm hoping a
new shell isn't spawned with a new enviorment). If this doesn't work my next
thought is
Use FvwmCommand with Echo (from fvwm) which can echo a string to your stderr
($HOME/.xsession-errors is common for this). Then parse the value from
$HOME/.xsession-errors with grep/regex tools. This should work with either
EnvVars or InfoStore since you can echo their values as well. The only issue I
see with this portability as not everyone may have stderr of their Xserver
redirected to $HOME/.xsession-errors
