In the triage view the images scale up to fit the window beyond 100% of the actual image size if the window is large enough.
I'd prefer that they don't scale up larger than actual size by default.
Displaying the current zoom would be nice so I know whether I'm looking at a scaled down image or not.
I wonder if the js/html needs to consider the device-scale so that images are pixel-exact on high dpi displays (e.g. retina mac, android).
Zooming beyond 100% might be useful as an option. I think I'd want it to always be nearest-neighbor sampled and always an integer scale.
