Detailed Description

Everything about the mipmap cache that the USER decides.

These four were read from conf at the point of use, so the cache depended on the configuration system and its behaviour could change under it mid-decode. They cross the boundary as one value now: the application reads conf, the cache is told. That also makes the lifecycle visible – set once at startup, set again when the user changes a preference, and never anywhere else.
