EngineDimension: [number | undefined, number | undefined] | undefined | number

Type of dimension for engine; can be a tuple of boundaries, a single static dimension or undefined for container size. When using a tuple to specify boundaries [min, max], actual size for engine will be the size of its container clamped to the specified pixel boundaries. Any of the values inside the tuple can be undefined. Using a single number will set a static size for engine dimension, meaning no resizing of engine will take effect.
