[Qt-qml] Rounded Corner Clipping Support in Rectangle

Depending on the background that is below the image you want to clip,
one obvious option would be to add a BorderImage on top of the
content, and make the BorderImage's content transparent except for the
corners (so that they overdraw what's below them). Of course, it
depends on what background image you have, but basically, this allows
you to emulate rounded corners (or any shape, basically) with an
"overlay" image + rectangular clipping.

HTH.
