Nit: Instead of being so detailed here about the uses of this class, I'd just
say something simple and leave users to document things in more detail:

"View used to draw a bubble containing an optional icon followed by a label. 
This is used for e.g. the EV bubble and the tab-to-search UI."

Done.

 class IconLabelBubbleView : public views::View {
  public:
+  // Set |contained_image| to -1 if there's no icon.

I think in this case it would be OK/cleaner to have an overloaded constructor
without contained_image. Up to you.

[Peter Kasting, 2012/12/05 21:13:20]

Because the two constructors' implementations would be so similar, I'd weakly
rather not.

   IconLabelBubbleView(const int background_images[],
                       int contained_image,
                       SkColor color);
