btw, at the risk of venturing off topic, a side note that no one has brought up: libglvnd also introduces a new gl ABI.. in addition to the compat libGL.so which for historical reasons drags in GLX and X dependencies, also provides libOpenGL and a separate libGLX (so you can use, for example, libOpenGL + libEGL with no X11 dependencies). That is a pretty nice, and long overdue, cleanup, IMHO.
