When drawing adjacent triangles it's useful to avoid drawing the same edge twice so we get consistent rendering. By convention, top and left edges are drawn and bottom and right edges are not.
For this change, we need to add an Earthrise option bit for filled triangles that controls whether we implement the top-left rule.
Consider this for rects too.
