Detailed Description

A widget's size request in both dimensions, and the bounds its extent is clamped into.

A bound clamps the extent the sizing gives, whatever the sizing: a stretch child's share stops at its maximum and a content or fixed child takes at least its minimum. A negative bound, a minimum above its maximum and a fixed amount outside its bounds are refused at mount (std::logic_error).
