[glom] Print Layout: Make the manipulators the same width as the outlines.

[Murray Cumming <murrayc src gnome org>]

commit 953940e317dfdde7651dc1c7d744e054a178e891
Author: Murray Cumming <murrayc murrayc com>
Date:   Thu Aug 11 17:54:26 2011 +0200

    Print Layout: Make the manipulators the same width as the outlines.
    
    * glom/utility_widgets/canvas/canvas_group_resizable.cc: Change
    MANIPULATOR_STROKE_WIDTH to be the same as OUTLINE_STROKE_WIDTH,
    which is thinner.
    create_outline_line(): Prevent dragging of the outline, in case it
    ever gets high enough in the z order to be dragged.
    create_rect_manipulators(), position_line_manipulators(),
    create_outline_line(): Always raise the manipulators to the very top,
    so they are always visible and draggable. Trying to be more precise
    with raise() can apparently move them lower than other items that we
    do not mention.
