Description

JPEG supports decoding an image at a smaller resolution, which is faster and uses less memory.
This can be useful when we're trying to decode a very large JPEG just to downscale it using `tiny-skia` anyway.

Research direction

Start by locating the JPEG decoding path and how decoded images are passed to tiny-skia for downscaling. Determine how to request a smaller decode for large JPEGs, then verify that oversized images use less decoding work and memory while producing the expected downscaled result.
