This extension is a wrapper around VIPS, a free image processing software. VIPS is a set of image manipulation tools specially designed for speed and low memory usage. This is useful for resizing large PNGs.
The extension shells out to the vips binary. It can be configured to scale only certain files (for example: big PNGs) by configuring $wgVipsConditions.
The Wikimedia Foundation is testing out using it on test2.wikipedia.org, but it isn't deployed on any major WMF wikis yet.
