title: Transparent PNG image (with TImageList) in a TMainMenu
body: <p>I want to load a PNG with transparent background in a TImageList and use it in a TMainMenu (via TAction).<br />
  However, in Delphi the background is just black.</p>
  <p><a href="https://stackoverflow.com/questions/4814971/transparent-png-image-with-timagelist">This</a> guy says it worked for him, but with a button instead of a main menu.</p>
  <p>My setup:</p>
  <ul>
  <li>My image is 8 bit per color plus 8 bit for transparency channel (I have tried also with 1 bit for transparency but still doesn't work). The image looks just fine in any other program.</li>
  <li>Delphi XE.</li>
  <li>In TImageList's editor, the 'transparent color' and 'Fill color' are set to 'Default' and are disabled.</li>
  </ul>
