/*
* WorldView.m
*
* WorldView is a subclass of View. It simply displays and clears a message in
* the view. The one lesson this example shows is the modification of
* "drawSelf::" and the call to "display". The method, "drawSelf::", should
* not be called directly.
*
* Rather, "display" should be called. The display message performs
* some necessary overhead such as bringing the View into focus by
* constructing a clipping path around its frame rectangle and making its
* coordinate system the current coordinate system for the application. The
* display method then messages drawSelf::. These steps are repeated for
* each of the View's subviews.
*
* Note: Any instance variables that need to be initialized before the first display
* should be done in the "init" or "initFrame:" method. In this case,
* drawHello is already a null value at its creation so no initialization
* has to be performed.
