OK I would like to come back to this: Shouldn't eglCreateContext with
EGL_CONTEXT_CLIENT_VERSION = 2 create an Open GL ES 2.0 compatible
context?

On my machine this seems broken somehow. Steps to verify this:

Build mesa-demos and start es2tri. It stops with

| x_window: Assertion `val == 2` failed.

The code is creating a context for 2.0 and checks if the desired
version was accepted:

   static const EGLint ctx_attribs[] = {
      EGL_CONTEXT_CLIENT_VERSION, 2,
      EGL_NONE
   };
<...>
   ctx = eglCreateContext(egl_dpy, config, EGL_NO_CONTEXT, ctx_attribs );
<...>

      EGLint val;
      eglQueryContext(egl_dpy, ctx, EGL_CONTEXT_CLIENT_VERSION, &val);
      assert(val == 2);

For me this seems to turn into a serious issue - suggestions?
