This would allow to draw UI elements (such as indent lines or a fill column indicator) and eye candy like background images or colored windows. This two first features (indent lines and fill indicator) are controlled by declaring a list of vertical segments linked to buffer positions. Is there any other feature that could be implemented like this? Not just by segments, but by any graphics drawn behind the text, vectors or bitmap. Thanks.
