bugref:8611:3D: X11 Guests ignore CR_VBOX_CAP_HOST_CAPS_NOT_SUFFICIENT: Check for the CR_VBOX_CAP_HOST_CAPS_NOT_SUFFICIENT host capability in the X11 Additions too, and disable 3D pass-through if it is found. This means that the host only supports OpenGL 2.0 or older, most likely Windows host software rendering.
