Bug 759:

Currently, the compatibility context on Mesa >= 9.1.3 seems to be
very broken. The core contexts, however, seem to be quite stable. This
commit both reduces and widens the scope of the current Mesa quirk to
include only Compatibility contexts on OpenGL > 3 || 3.n where n >= 1.
Merge branch 'master' of ssh://jogamp.org/srv/scm/jogl into mark
Remove redundant check around Mesa quirk (that check has already occurred via isDriverMesa)
Merge remote-tracking branch 'mraynsford/mark'
