        Fixes from #98358, Havoc Pennington.

        * gdk/{x11,win32,linux-fb}/gdkcolor-*.c (gdk_colormap_finalize):
        Free the private structure.

        * gdk/x11,win32,linxu-fb}/gdkscreen-*.c (gdk_screen_set_default_colormap):
          gdk/x11/gdkwindow-x11.c (_gdk_windowing_window_init):
        Keep a ref to the default colormap.

        * gdk/x11/gdkscreen-x11.c (gdk_screen_x11_dispose): Unref
        the default colormap.

        * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap):
        Handle the CMAP == NULL case even when the window is
        destroyed.

        * gdk/x11/gdkwindow-x11.c (_gdk_windowing_window_init):
        Add a missing ref for the system colormap.
