title: Making a "pressing" effect on a TextButton with a shadow
body: <p>I'm currently generating the font for my TextButton with a shadow, using FreeType. I would like to do something so that when I click on the textbutton, the text is moved a bit down and to the right, simulating a press. The shadow shouldn't move. Here's and example of what I mean:</p>
  
  <p><a href="https://i.stack.imgur.com/CsyY0.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CsyY0.gif" alt="Example"></a></p>
  
  <p>Notice how the shadow doesn't move. How can I accomplish something like this? I suspect it has something to do with drawables, but I'm not sure. Help is very much appreciated!</p>
