Description Javier Fernandez 2014-07-31 06:04:44 PDT 
The CSS3 Box Alignment  specification (http://dev.w3.org/csswg/css-align-3) defines new values for the align-{self, items} CSS properties. 

Currently, the RenderFlexibleBox render does not support the following ones:
  - start
  - end
  - self-stat
  - self-end
  - left
  - right
  - last-baseline (at risk of being dropped during the CR period)
