This commit reimplements the (normally) 45 degree (depends on the widths) connection between to adjacent borders. Which is needed to paint the 'caret' icon seen in a few buttons on GitHub. The issue of overlapping pixels while painting this has also been solved for the 45 degree case (the the most likely case, the other cases only occur of mixed-with borders).
