title: UIToolbar UIBarButtonItem with both image and title has very dim text
body: <p>My iPhone view adds some custom buttons to its toolbar. Each button has both an image and textual title, and is created like this:</p>
  
  <pre><code>UIBarButtonItem *fooButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"foo.png"] style:UIBarButtonItemStylePlain target:self action:@selector(fooButtonPressed:)];
  fooButton.title=@"Foo";
  </code></pre>
  
  <p>The title's text displays very dim; it looks like it has an alpha of about 0.5. If I use the default UIToolBar barStyle, I can't read the text at all. When using UIBarStyleBlack I can read the text but it still looks very dim.</p>
  
  <p>I also tried initWithTitle, and then set the image property; the results are identical.</p>
  
  <p>Is there a way to brighten up the text? I am hoping for a look similar to a UITabBar whose items have both an image and title.</p>
  
  <p>Thanks for the help!</p>
