    Bug: tessellator sometimes ends rightmost trapezoids too late
    
    Reported on the cairo mailing list:
    
    http://lists.cairographics.org/archives/cairo/2008-May/014233.html
    
    The tessellator would sometimes produce self-intersecting trapezoids
    because it would skip the last edge in the active list when deciding
    whether we can continue the current trapezoid or not.
    
    The bug never caused a problem with pixman based rasterisation
    because pixman stops filling in a trapezoid once it detects a self
    intersection.
