body: <p>I'm using WPF 3.5 SP1 and I want to achieve something like this (the glass-part is already done):</p>

  <p>You can see nice blur around the text, which makes it very well readable. I also found out that correct approach is to use API <code>DrawThemeTextEx</code>, which renders the blur using recommended system options. However, how can I achieve the same effect using WPF?</p>
  
  <p>I was able to find these links which contain helpful resources:<br>

  <p>They do it by duplicating the TextBlock, and setting a Blur effect on it. However, this is not a real solution. Here is how it looks like:</p>

  <p>Compare the result effect with the images above, and you will see the solution is still far away. So how can I properly get the desired effect using WPF? I'm fine with emulation (no use of <code>DrawThemeTextEx</code> API), as far as the result is pretty similar.</p>
  
  <p>Thank you.</p>
