Designed a new system for doing hierarchical displays in the canvas. Adds

2000-03-10  Christopher James Lahey  <clahey@helixcode.com>

        * e-util/e-canvas.c, e-util/e-canvas.h: Designed a new system for
        doing hierarchical displays in the canvas.  Adds an extra idle
        loop to the canvas system.

        * widgets/e-minicard/e-minicard.c,
        widgets/e-minicard/e-minicard-label.c,
        widgets/e-minicard/e-minicard-label.h,
        widgets/e-minicard/e-reflow.c, widgets/e-minicard/test-reflow.c,
        widgets/e-text/e-text.c, widgets/e-text/e-text.h: Adapted to use
        the new e-canvas reflow system.
