It might be the other way around; that is maybe our graphics guys can
help the Glean and Piglit developpers.
Quite often they discover some bug in OpenGL. But if neither Glean nor
Piglit tests for these specific bugs then it's no wonder that one OpenGL
driver or another gets it wrong. So they may have ideas of tests to add
to Glean and Piglit.
A number of issues are with OpenGL extensions. I don't know what Glean's
and Piglit's policies are with regards to those. Hopefully they test
them too. Maybe, just maybe, OpenGL drivers developers will feel a bit
less free to ignore a given OpenGL extension if it has a test suite.
Porting it to Mac OS X (either through Apple's X server or natively)
would probably also expose a bunch of bugs.
All that would help us indirectly of course: through hopefully better
quality OpenGL drivers. So one day they would only have to deal with D3D
bugs and no longer with OpenGL ones (one can dream).
But it's more work in the short term. Also it all assumes that Glean and
Piglit are actually used by driver developpers (though they could also
be useful for reporting bugs).

Any sufficiently advanced bug is indistinguishable from a feature.
