//
// A ClientView is a View subclass that is used to occupy the "client area"
// of a window. It provides basic information to the window that contains it
// such as non-client hit testing information, sizing etc. Sub-classes of
// ClientView are used to create more elaborate contents, e.g.
// "DialogClientView".

// contents. Since this object is created during the process of creating
// |window|, |contents_view| must be valid if you want the initial size of
// the window to be based on |contents_view|'s preferred size.

// implementation. If it is outside the bounds of this view, this must return
// HTNOWHERE to tell the caller to do further processing to determine where
// in the non-client area it is (if it is).
// Subclasses of ClientView can extend this logic by overriding this method
// to detect if regions within the client area count as parts of the "non-
// client" area. A good example of this is the size box at the bottom right
// corner of resizable dialog boxes.
