-// 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.
-//
