  <para>
    #cairo_t is the main object used when drawing with cairo. To
    draw with cairo, you create a #cairo_t, set the target surface,
    and drawing options for the #cairo_t, create shapes with
    functions like cairo_move_to() and cairo_line_to(), and then
    draw shapes with cairo_stroke() or cairo_fill().

    #cairo_t<!-- -->'s can be pushed to a stack via cairo_save().
    They may then safely be changed, without loosing the current state.
    Use cairo_restore() to restore to the saved state.
