Description
This object is a subclass of Array. It represents a bounding box as 4 elements with accessor aliases `x-min`, `y-min`, `x-max` and `y-max`.
Methods
`x-min`, `y-min`, `x-max`, `y-max`
The bottom-left and top right coordinates of the bounding box. These can also be accessed as a four element array.
`width`, `height`
Aliases for `x-max - x-min` and `y-max - y-min`.
`x-scale`, `y-scale`
The bounding `x` and `y` scale of the bounding box.
