// 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.
