The problem with the 'placing overlapping brush pixmaps' approach is only really obvious at very narrow line widths. IMHO, the pencil tool should be left alone for consistancies' sake and there should be a new tool to deal with the very special case of drawing single-pixel-wide hard-edged lines. This hypothetical gadget could use Bresenham's algorithm or something like that because it wouldn't *NEED* to deal with pixmaps and need only hit pixels dead-on. > I really like this idea since the > old functionality of the pencil tool could be easily implemented in > the paintbrush (all we'd have to do is to add a "Hard edge" option > like the Eraser has) and having a real line-drawing tool would be a > major benefit. Yes.
