Pass Custom TabBarRender to FloatLayout?

[mhallrt]

Hey thanks for such a great addition to the phosphor library. I'm trying to render a custom tab bar, so I would like to pass my own renderer to the the DockLayout contained inside FloatLayout. Any way we can configure the FloatArea to pass the render to the FloatLayout which then uses it to instantiate the DockPanel?

Also on an unrelated note, do you have a standard way to integrate this with saving and restoring?
Currently I'm extending the FloatArea class, then overriding the processMessage method to listen for a couple events like "dialog-update" to save the current absolute position of the div, as well as call "saveLayout" on the underlying DockPanel in order to restore the layout later on. It works, but I'm wondering if there is a better way?
