title: Rect's equivalent to text's text-anchor presentation attribute?
body: <p>Is there a rect's equivalent to text's text-anchor presentation attribute?</p>
  
  <p>I want to be able to position a rect from its left/right side or depending on the situation. I know that it could be done with some simple calculations, but I'm just wondering if something already built-in exists.</p>
