As far as I can tell from the GLUT sources, the game mode stuff works only
with WinDoze and is basically a no-op on other platforms. This has nothing
to do with HOpenGL, it's GLUT itself which is incomplete.

Ooops, this is just a plain oversight: Simply add GameModeCapability and
GameModeSetting to the export list of GLUT_Game.gc.in.
