Justify() vs Normalize()

[Chris Sherlock]

Hi all,

I only recently discovered that tools::Rectangle::Justify() really means that the 
rectangle is normalized (I.e. the points are arranged in such a way that the width is always positive, and the x and y coordinates are in the the top left corner).

Would it be possible to rename it to Normalize(), or at least add Normalize() as an an alias that calls on Justify()?
