The glx string is the intersection of client and server strings (think
least-common denominator).  GLX_ARB_get_proc_address (and probably
GLX_SGIX_visual_select_group) don't have a server side component (i.e.
client-side only) and so these are automatically added.  Other than client-side
only extensions, only extensions which exist on both the server and client are
shown in the glx string.

Hope that helps.
