Fix bug 564 (X11 Mesa 8.0.1 GL 3.0 w/o GLX_ARB_create_context)
X11/Mesa 8.0.1 offers a GL 3.0 context w/o having the GLX_ARB_create_context extension available (even though the func-ptr glXCreateContextAttribsARB is not null). We assumed that if no GLContext device availability is set, it can be only GL 2.0 or ES1/ES2. Fix: Relaxed these (false) constrains and map the created context reflecting using it's actual attributes.
