[Murray Cumming <murrayc src gnome org>]

commit cbb549d2bf19e7c4bba6a3bf38d4092b67074790
Author: Murray Cumming <murrayc murrayc com>
Date:   Sun Aug 7 23:21:50 2011 +0200

    Print Layout: Improve the grid appearance.
    
    * glom/mode_design/print_layouts/window_print_layout_edit.cc:
    on_menu_view_show_grid(): Use a smaller grid gap, which seems more useful.
    * glom/utility_widgets/canvas/canvas_group_grid.cc:
    create_rule_line(): Make the lines thinner and light blue instead of
    gray.
