My bad, depending on how you create your QGLWidget's, you can also tell
them to share with each other. (I wasn't using this technique, and so
wasn't recalling it offhand.)

OTOH, depending on how you create your widgets, this may not be
possible. (For example, if your widgets are defined in a .ui file,
you'll need to invoke some cleverness in your subclass ctor to either
use a global sharing context you have previously created, or else
arrange for the first one created to set itself as the share widget for
the others.)
