Clarifying the documentation of ScatterLayout

The previous documentation was based in the old RelativeLayout (based in a Scatter). The documentation didn't indicate the difference between Scatter and ScatterLayout.

Scatter is already relative so the only difference that I can see is the possibility of using the hint properties.
