Transition: Iris Points

The "Iris Points" transition uses points closing in from the edges of the frame to reveal clip B.

This transition has many variations.

Make the border width greater than zero to draw a border around the points.
- You can choose the color of the border. The default is black.
Place a check in the "Reverse" checkbox to have the points open to reveal clip B.
You can specify the amount of anti-aliasing used to soften the edges of the points. The default is "off".
