// View class
//
//   A View is a rectangle within the views View hierarchy. It is the base
//   class for all Views.
//
//   A View is a container of other Views (there is no such thing as a Leaf
//   View - makes code simpler, reduces type conversion headaches, design
//   mistakes etc)
//
//   The View contains basic properties for sizing (bounds), layout (flex,
//   orientation, etc), painting of children and event dispatch.
//
//   The View also uses a simple Box Layout Manager similar to XUL's
//   SprocketLayout system. Alternative Layout Managers implementing the
//   LayoutManager interface can be used to lay out children if required.
//
//   It is up to the subclass to implement Painting and storage of subclass -
//   specific properties and functionality.
//
//   Unless otherwise documented, views is not thread safe and should only be
//   accessed from the main thread.
