The latter is (supposed to be) common sense.

The documentation is certainly lacking. Are you volunteering... never

Not in general. Just as one example, Cedega uses glxgears for this, but
it incorrectly thinks that there's no hardware acceleration when
sync-to-vblank is enabled.
glxgears is a very simple program that demonstrates the use of GLX to
display three rotating gears. Nothing less, but especially nothing more.
