Comment (by nacin):

 I'm with wonderboymusic on this being a pre-commit tool rather than a
 build tool. It can essentially be in the same boat as autoprefixer
 (#27078). Maybe we'll hook it up to build later, but I think just having
 the task there is a good first step.

 Since it'll be applying these changes directly to files in `src`, we need
 to be really restrictive of which images we apply them to. I made it
 imagemin:core as imagemin:themes makes sense in the future. That said, all
 of our theme screenshots are currently perfect, and the optimization of
 jpeg header images and such is something that is done by hand — balancing
 quality for file size. So rather than coming up with a rule that would
 essentially be just screenshots, I left it out for the moment.
