Shrink an image before it is uploaded, and hand back the original whenever
that would not be an improvement. No canvas in this environment, a file
already small enough to leave alone, a format re-encoding would ruin, or a
result that came out no smaller than what we started with. Callers can
therefore run this unconditionally and never make a file worse.
