RectOffsetPOD for Unity3D (since UnityEngine.RectOffset likes to throw “ArgumentException: set_left can only be called from the main thread.” if used as a field initialier)

RectOffsetPOD.cs

/// @creator: Slipp Douglas Thompson
/// @license: Public Domain per The Unlicense.  See <http://unlicense.org/>.
/// @why: Because UnityEngine.RectOffset fields should be able to be initialized without throwing ArgumentExceptions (last observed 4.5.2f1).
/// 	Also, UnityEngine.RectOffset should probably be a struct, not a class.  So a struct form like this is necessary for some software patterns.
/// @intended project path: Assets/Plugins/UnityEngine Extensions/RectOffsetPOD.cs
/// @intersource: https://gist.github.com/capnslipp/87d944e474ca701eca8b
