Badly worded, really.

libGL.so includes the GLX API entrypoints, so your libGL will link to
X11. For that reason - and because there's no need for it to use full
GL - Weston uses GLES2 for its own composition. For clients, if you
don't care about this, then you can use libGL + EGL (this has always
worked), or there's also libglvnd's libOpenGL (this is new). Given
that, it should be reworded.

Cheers,
Daniel
