+    and force the display of state numbers, the actual state names
+    is now moved to the "tooltip" field of the state.  The SVG

   - cleanup_parity() and cleanup_parity_here() are smarter and now
     remove from the acceptance condition the parity colors that are
     not used in the automaton.

+Note that labeling states with names (the first line) and the

+produce graphs with large nodes that are problematic to render.  A
