Shape tab
The shape of any control (picture, video, movie, browser, etc) is rectangular by default. You can change this to any of the standard shapes here, for example a circle or triangle. However, you can additionally specify a shape for the contents. For example, you can have a rectangular picture control, but the picture inside can be shaped as a triangle. Setting the background colour of the control to that of the screen background will give a higher quality effect.
