New Behavior

    To request a display that translates to OpenGL or OpenGL ES, the value of
    EGL_PLATFORM_ANGLE_TYPE_ANGLE should be:
      - EGL_PLATFORM_ANGLE_TYPE_OPENGL_ANGLE for an OpenGL display,
      - EGL_PLATFORM_ANGLE_TYPE_OPENGLES_ANGLE for a native OpenGL ES display.

    To request a specific maximum context version to use for the underlying
    API, EGL_PLATFORM_ANGLE_MAX_VERSION_MAJOR_ANGLE and
    EGL_PLATFORM_ANGLE_MAX_VERSION_MINOR_ANGLE can be used.

Issues
