Sets the background color of window. (However, when using GTK+,
set the background of a widget with gtk_widget_modify_bg() - if
you're an application - or gtk_style_set_background() - if you're
implementing a custom widget.)
The color must be allocated; gdk_rgb_find_color() is the best way
to allocate a color.
