Pbuffer support in JOGL seems to be broken on all X11 platforms. The JGears demo
shows either garbage or nothing for the OpenGL view. Something must have been
broken during the recent code refactoring to make pbuffers and on-screen
drawables share the same pixel format selection code path. This issue was
reported by Paul Butcher from Advanced System Architectures UK.

It turns out that pbuffer support wasn't completely broken, but the
GLX_DOUBLEBUFFER bit wasn't being set properly for single-buffered windows and
pbuffers, which mattered in particular for the JGears demo (and the GLJPanel)
which read back the contents of the front buffer.
