        * gdk/x11/gdkcolor-x11.c (gdk_colormap_alloc1): Fix
        a lost refcount in the case where we get a duplicate
        back from the X server.

        * gdk/x11/gdkcolor-x11.c (gdk_colormap_alloc_colors_writeable):
        Set success[] for all colors when allocation of colors
        cells via XAllocColorCells succeeds.

        * gdk/x11/gdkcolor-x11.c (gdk_colormap_alloc_colors_private):
        Don't match against colors cells allocated writeable.
