There is a bug in the X11GLDrawableFactory.glCapabilities2AttribList method that
prevents an app from selecting a single-buffered visual on X11 platforms. That
method treats GLX_DOUBLEBUFFER as if it were an attribute that takes a boolean
parameter, which is incorrect for glXChooseVisual. The GLX_DOUBLEBUFFER
attribute takes no parameter, rather its presence indicates that a double
buffered visual should be selected. This bug causes two problems. First, if a
single-buffered visual is requested, the request will not be honored. Second,
the "false" value will be interpreted as "None" causing all subsequent
attributes to be ignored.

Btw, you need to be careful when fixing this bug if the output of this method is
ever used by glXFBConfig, which *does* treat GLX_DOUBLEBUFFER as a boolean
attribute that takes a parameter.

One more thing. The GLX_STEREO attribute is being set correctly for
glXChooseVisual and, as such, is currently incorrect when used by glXFBConfig.
In other words, it has the opposite problem of GLX_DOUBLEBUFFER.

Fixed GLX_DOUBLEBUFFER and GLX_STEREO specifications for both
on-screen and pbuffer visuals as per suggestion.
