        * widgets/e-canvas-utils.c, widgets/e-canvas-utils.h:
        e_canvas_item_move_absolute is just a helper function not supplied
        by the gnome_canvas.[ch] I put it here so that multiple items can
        use it.

        * widgets/e-reflow.c, widgets/e-reflow.h: This item contains a
        number of other items and places them into multiple columns.  The
        items contained must support a number of arguments and signals to
        allow the reflow to interact with them.

        * widgets/test-reflow.c: This is a test program for e-reflow.

        * widgets/e-text.c, widgets/e-text.h: Added properly drawn
        selected text.  Added some preliminary code for X selection
        handling and cut & paste.

        * widgets/e-minicard.c, widgets/e-minicard.h: Added ARG_HAS_FOCUS
        handling.  Made label display random for more interesting tests of
        multiple cards.  Tweaked sizing information for better display.

        * widgets/e-minicard-label.c, widgets/e-minicard-label.h: Added
        ARG_HAS_FOCUS handling.

        * widgets/Makefile.am: Added the reflow test and reflow files.
