Doesn't appear to honor custom styles/directives

[StingyJack]

Using the example from the nomnoml site I would expect this to be a green dashed box, but the viewer doesnt apply this style.

#.box: fill=#8f8 dashed
[<box> GreenBox]

Trying to use other properties doesnt work either (visual=actor, etc).

Is my expectation wrong or is this missing?
