Box is a convenience layout + drawing primitive. Container proved itself as a layout people need, but we can go further and add some drawing in it, by simplifying DrawModifiers understanding and while also providing API people expect.

As this is kind of fresh start for Container -> Box story, we can break and change API to replace parameters set with more well-thought options without conflicts and ambiguity.

Decided to go with incremental story, by introducing Box first, then seeing how it plays out, fixing whats wrong and only then deprecating Container.
