BoxConstraints
    Constraints that must be respected by a size of a box.
A Size respects a BoxConstraints if, and only if, all of the following relations hold:
min_width <= Size.width <= max_width
min_height <= Size.height <= max_height

    The maximum height that satisfies the constraints, such that
min_height <= max_height <= float("inf").
    The maximum width that satisfies the constraints, such that
min_width <= max_width <= float("inf").
min_height: Number = 0
The minimum height that satisfies the constraints, such that
0.0 <= min_height <= max_height.
