Commented Issue: GraphvizEdge.ToDot() wrong graphviz properties [22051]

Mappings for FontGraphvizColor and StrokeGraphvizColor are wrong, so it is impossible to change edge stroke and font color.
 
Replacement:
fontGraphvizColor → fontcolor
GraphvizColor → color
 
Seems like URL property is also invalid (http://www.graphviz.org/doc/info/attrs.html).
Comments: ** Comment from web user: CSP **

Also,
```
bgGraphvizColor → fillcolor
```
