Certain applications don't call SwapBuffers before exiting. Yet,

In particular, Piglit tests (at least with -auto -fbo) fall into this
category. Many of them failed to dump any images at all.
Dumping one final image at context destruction time seems to solve
the
issue.
Another alternative would be for piglit and mesa should use/implement
http://www.opengl.org/registry/specs/GREMEDY/frame_terminator.txt , so that the
whole stack has a precise knowledge of where frames are.
Would having the piglit framework call glFrameTerminatorGREMEDY after
calling piglit_display be sufficient? That ought to be easy enough.
One the Mesa side, I think most apps only use glFrameTerminatorGREMEDY
in debug builds, so it might not be that helpful here.
