This sample demonstrates how to display and print text using a CScrollView
derived class. It is possible to implement text output in a CScrollView
class by overriding OnDraw, and drawing the entire document using TextOut.
However, further steps are required to draw the text efficiently, and to
include support for multipage documents. Here are the features implemented
in this sample, and the locations:
