title: Is there an API in QML similar to setMask() API of QT?
body: <p>We want to make a particular region of a QML rectangle transparent.</p>
  
  <p>In case of QT, to do the same thing, we have used the setMask API of QWidget.</p>
  
  <p>Is there any API in QML which does the same.</p>
  
  <p>What I feel is that we can use the pass the QML rectangle to the QT cpp file and use setMask() API on the rectangle, but will this be possible?</p>
  
  <p>Thanks,
