+// Border class.
+//
+// The border class is used to display a border around a view.
+// To set a border on a view, just call SetBorder on the view, for example:
+// view->SetBorder(Border::CreateSolidBorder(1, SkColorSetRGB(25, 25, 112));
+// Once set on a view, the border is owned by the view.
+//
+// IMPORTANT NOTE: not all views support borders at this point. In order to
+// support the border, views should make sure to use bounds excluding the
+// border (by calling View::GetLocalBoundsExcludingBorder) when doing layout and
+// painting.
