Fit Box
Fits a box within a boundary while keeping its original aspect ratio.
The box will either be scaled up or scaled down within the boundary:
fitBox({
boundary: { width: 400, height: 300 },
box: { width: 20, height: 60 },
});
// => { width: 100, height: 300 }
fitBox({
boundary: { width: 400, height: 300 },
box: { width: 1280, height: 760 },
});
// => { width: 400, height: 237.5 }
