> and are very careful about preserving image metadata (including Exif,

> totaling hundreds of GB) very efficiently using only a tiny amount
> (tens of megabytes at most) of runtime memory. Additionally, a
> TextureSystem class provides filtered MIP-map texture lookups, atop
> the nice caching behavior of ImageCache.
