title: What window message applications receive on screen text size change
body: <p>A user has an ability to change a scale of displayed text (via <em>Settings → Display → Change the size of text, apps and other items</em> on Windows 10, for example).</p>
  
  <p>What window message should I process to be aware of such changes?</p>
  
  <p>I have a stuff which size depends on actual font height. However, size ajustments are time consuming so I would prefer not to perform them on each <code>WM_PAINT</code> arrival.</p>
