Oops, fix a perf regression in Hi-Res Mode!

Browse source 
Ah oops, because I forgot to set `hiResMode` here in the image preloader, we would preload the PNG, and _then_ load the SVG separately.

This doubled the effective image loading time in Hi-Res Mode!

Now, the image preloader respects hi-res mode, and will preload the SVG in the SVG case, and the PNG in the PNG case.
