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