- *  Principles:
- *    
- *    1. layout is defined by subdividing
- *    2. a parent node should never be resized by the content after creation
- *    3. when the ui is in an interactive state, no controls should ever move
- *    4. controls directly reference a memory location and use that as their
- *       unique id
- *    5. a maximum of ONE control per memory location can be drawn at any given
- *       point.
