NSOutlineView + Pattern as Background

[stuffmc]

You might want to just merge the OutlineView commit but I'm wondering if there's a way to have this work when the background of the Backing View isn't a plain colour.

I'm curious about what happens if you just try to set the background color of your outline view (what do you see?).

That: http://twitpic.com/befr1d — but as soon as I "disclose" my first node the whole thing is filled with nodes and then the shadow completely disappears. Try it for yourself — I've just put a small Demo app (without your code yet) at https://github.com/stuffmc/TreeBindings

Ah, I see. I wonder if JLNFadingScrollView would be better suited to your needs. If I recall correctly, I turned off background drawing in the outline view and let the scroll view's background show through. I think we've hit the limits of what this (recessed source view) can do, which is why I developed the fading scroll view. You should be able to set any background color/pattern you like since the fades are really just views tiled atop the content.

If you have no objections, I'd like to see what you find using JLNFadingScrollView before I merge this pull request.
