        If there are multiple lines of text, DrawText uses the width of the \
        rectangle pointed to by the lpRect parameter and extends the base \
        of the rectangle to bound the last line of text. If the largest word \
        is wider than the rectangle, the width is expanded. If the text is less \
        than the width of the rectangle, the width is reduced. If there is only \
        one line of text, DrawText modifies the right side of the rectangle so that \
        it bounds the last character in the line. In either case, DrawText returns \
        the height of the formatted text but does not draw the text.";
