If you know the SHM ID (which can always be obtained by setting
VGL_VERBOSE=1), then you can always just run 'vglconfig -shmid {id}'
from another console window. Thus, I'm not really interested in adding
a separate app that only tweaks one parameter, although I appreciate the
contribution. I would be potentially interested in a command line
interface for vglconfig that was more generic and allowed setting any
configuration parameter (for instance, 'vglconfig -shmid {id}
VGL_FPS=30') on a running instance of VGL.
Also it should be noted that any 3D app can be made "VirtualGL-aware"
and can provide its own means of tweaking VirtualGL's configuration
parameters by means of simply using setenv() to modify the environment.
The VirtualGL environment is re-read each time a frame is read back.
