     Gets a colormap to use for creating windows or pixmaps with an
     alpha channel. The windowing system on which GTK+ is running may
     not support this capability, in which case 'NULL' will be
     returned. Even if a non-'NULL' value is returned, its possible
     that the window's alpha channel won't be honored when displaying
     the window on the screen: in particular, for X an appropriate
     windowing manager and compositing manager must be running to
     provide appropriate display.
