------- Additional Comments from opendarwin.org at mitzpettel.com
I think this patch does not add a lot of painting, and what it does add can be
divided between
1) what's needed to fix the bug: the layer did not need layout, but ended up
resizing because of a child.
2) addressing the fact that the selfNeedsLayout() condition in
repaintAfterLayoutIfNeeded() is always false when called from the layer.
