Pack layout should allow parent padding? (“Margin”?)

Related d3/d3#2536; see demo.

I’m not sure about the name “margin”; maybe it’s worth having sibling padding and parent padding? Or maybe padding should automatically apply to the parent circle, not just the siblings.

I like the idea of having just one padding that applies to both parent and siblings.

[mbostock]

Seems reasonable to me, too.

Related question: Should the padding be configurable per node? Seems like you could compute the padding per node if it is specified as a function, and it would apply to padding between that node and its children (parent-child padding), and amongst its children (sibling padding).

Related #9.

Yep, it would certainly be good to have it configurable per node as well. Sounds like d3/d3#2473 would be a more general solution to this.

Fixed.
