+Subject: tor-scan-converter: can't do_fullrow when intersection in row +
+ 0.5subrow
+
+the active edges list must be left sorted at the next possible use
+and since full_row does not deal with intersections it is not usable
+when there is an intersection in the top half of the next row first
+subrow
