title: Are preferred font sizes in Windows8 going to require a calculator?
body: <p>While looking at some official Windows8/"Metro" material, I see this line of xaml:</p>
  
  <pre><code>&lt;TextBlock Text="Contoso Cookbook" FontFamily="Segoe UI" FontWeight="SemiLight" FontSize="26.667" /&gt;
  </code></pre>
  
  <p>What?!? A font size of 26.667? I realize this is 2/3rds of 40, and 5/6ths of 32, so maybe there's some conversion thing happening there, but is this going to be the preferred way of setting font sizes, and if so, what are the guidelines for coming up with these seemingly random sizes?</p>
