I agree, it is strange. BUT you still need a way in ecore_x for OPENGL 
to work. In order to actually achieve that, we have to Open the Display 
using XOpenDisplay else when using things like nvidia closed binary 
drivers for example OpenGL would not be possible...they expect an X11 
*Display variable to be passed to them in order to operate correctly.

If we use strict XCB and open with xcb_connect only, then OpenGL would 
not function because XCB provides no *Display variable to pass to the 
OpenGL code. Thus we link to x11-xcb which provides an XOpenDisplay and 
Display variable that we can then reuse for OpenGL.
