Previously the Xlib renderer data was meant to be the first member of whatever the winsys data is. This doesn't work well for the EGL winsys because it only needs the Xlib data if the X11 platform is used. The Xlib renderer data is now instead created on demand and connected to the object using cogl_object_set_user_data. There is a new function to get access to it.
