Modify TUIKit example to show textview inside of a scrollview

ExampleAppDelegate.m

	/* TUINSView is the bridge between the standard AppKit NSView-based heirarchy and the TUIView-based heirarchy */
	TUINSView *tuiScrollViewContainer = [[TUINSView alloc] initWithFrame:b];
	[scrollViewWindow setContentView:tuiScrollViewContainer];
	
	scrollExample = [[TUIScrollView alloc] initWithFrame:b];
    scrollExample.backgroundColor = [TUIColor redColor];

    textView.autoresizingMask = TUIViewAutoresizingFlexibleWidth;
    textView.delegate = self;

}

- (void)textViewDidChange:(TUITextView *)textView {
    CGFloat heightOfText = textView.heightOfText;
    CGRect f = textView.frame;
    f.size.height = heightOfText;
    textView.frame = f;
    [scrollExample setContentSize:f.size];
}

gistfile1.m

//Add this to TUITextView
-(CGFloat) heightOfText {
    CGFloat height = [renderer sizeConstrainedToWidth:self.bounds.size.width].height; 
    return height;
}

Quick Q: This doesn't work when the line height is 1. Any fix?
