I've never used OSMesa, but isn't it supposed to be off-screen?  If
you want OpenGL ES and on-screen display, I would say that you need
EGL, and an EGL driver for the display server.  If you want OpenGL ES
and off-screen rendering, I would still say that you need EGL.  But I
may be able to write a dummy EGL driver for that.
