Summary Image upsampling is not gamma-correct

Steps to reproduce: Looked at an image while using a retina screen Actual results: Safari upsampled the image 2x (good), but didn't do take gamma into account. Expected results: Safari should use a gamma-correct image resampling algorithm. I made a demo / repro here: https://nico.github.io/hack/web/gamma-upsample.html Here's a detailed explanation: http://www.ericbrasseur.org/gamma.html Browsers fixed their downsampling in response to that page long ago, but not their upsampling.
