Defined at:

Filters the "BIG image" threshold value.

If the original image width or height is above the threshold, it will be scaled down. The threshold is used as max width and max height. The scaled down image will be used as the largest available size, including the _wp_attached_file post meta value.

Returning false from the filter callback will disable the scaling.
