title: How to add company logo to NavigationPage TitleIcon?
body: <p>So I'm trying to add a company logo to the middle of my <code>NavigationPage</code> Title section, and I have tried to use <code>NavigationPage.TitleIcon="companytitleicon.png"</code> inside <code>XAML</code>, but it doesn't display. I'm not certain if it's because the image has to be a certain size, and I cannot find information in the documentation.</p>
  
  <p>I played around with other code as well, like calling <code>NavigationPage.SetTitleIcon</code> which takes a reference to a page and a FileImageSource like so:</p>
  
  <p><code>NavigationPage.SetTitleIcon(this, "/Assets/dischemtitleicon.png");</code></p>
  
  <p>I may be using it incorrectly, so I need a bit of advice, in general, with getting the logo to display on the Title section. I'll add a screenshot as well to specify the location and size of the logo. The logo is at least twice as wide as the height, eg. <code>120 x 50</code> ...</p>

  <p>Any assistance will be truly appreciated. I'm also trying to get the colour of the <code>MasterDetail</code> bar to change, but that's not as crucial of an issue. (I added a global StaticResource that applies a fixed colour to all NavigationPage BarBackgroundColors)</p>
