blender/intern/ghost/intern/GHOST_WindowCocoa.mm
Brecht Van Lommel 24c0f1873e Fix part of #26850: Cocoa OS X game player was not working, two issues:
* Unlike blender, the game player draws only on windows update callbacks,
  and those wer not implemented.
* Going fullscreen for player was not implemented correct, it expected an
  existing window but actually it should create one.
