For table shape we used OWN_ATTR_BITMAP as the identifier for the
"RepalcementGraphic" property, but that is not really correct.
More correct would be to use OWN_ATTR_REPLACEMENT_GRAPHIC, which
name reflects exactly what the property is for and doesn't conflict
with OWN_ATTR_BITMAP which is used for the "Bitmap" property.
