New findings: followings are new findings

• three layout rule (parent will ask, child will decide, then parent locate children) looks simple, but it would become complicated easily, I guess.
• .frame, .frame(alignment), .offset looks intereseting, but looks it is not so easy to understand .lastTextBaseline for Japanese.
• making necessary alignment guide would be mandatory in some day.
• always it make me surprize enum works well instead of struct.
• I dont have fully understanding..., maybe need to come back later
