I need to work with a Rect that has Left, Top, Bottom, Right.
Unity's Rect has x, y, width and height instead.
Also, Unity's Rect doesn't accept Rect.Compare(otherRect).
System.Windows.Rect however seems a good choice for my needs.
I would like to ask if it's ok to use System.Windows.Rect in my Unity script and if it will be cross-platform.
