    gitlab#181 - Inherit attributes in <svg> element properly
    
    I accidentally removed the call to state_reinherit_top() in
    NodeSvg::draw().  Duh!
    
    Also, regenerated 761175-recursive-masks-ref.png.  It *was* being
    rendered incorrectly, with the caps at the end of the lines chopped
    off.  I didn't notice because they were very small in the resulting
    PNG.
