  Context: Bind current display/surface.
  
  Looking at the EGL spec, it says for eglGetCurrentDisplay:
  
  "The display for the current context in the calling thread, for the
  current rendering API, is returned."
  
  This implies that MakeCurrent binds a display to a Context. There's
  also pretty clear language for the read/draw Surface as well, that
  they can only be bound to one Context/thread at a time. Hence we
  don't need to duplicate this storage in the egl::Thread structure,
  merely storing a pointer to the current Context, which has access
  to the read/draw Surface and current Display.
