Changes for version 2.27

  • Stop using bare word file handles (again).
  • Change sub BUILD() in all sub-classes to check whether or not a 'graph' parameter was supplied to new(). If so, use it rather than instantiating a new GraphViz2 object. This fixes a problem with those script/*.pl demos which use this feature.
  • Fiddle t/sample.recdescent.1.dat, since the original test data happened to look like HTML, and that stopped GraphViz2.stringify_attributes() adding double-quotes to protect the label. That in turn caused dot to issue a syntax error when the generated DOT data was read.
