CoglXlibDisplay just contained one member called dummy_xwin. This was not shared outside of the respective winsys's so I don't think it really makes sense to have a separate shared struct for it. It seems more like an implementation detail that is specific to the winsys because for example it may be that the EGL winsys could use the surfaceless extension and not bother with a dummy window. This will also make it easier to factor out the Xlib-specific data in CoglDisplayEGL to the platform data. Reviewed-by: Robert Bragg <robert@linux.intel.com>
