Markus, is this wrapper in the library, or just in existing modules ? I know the version in the i.superpixels.slic addon and have some memory of you implementing it elsewhere.
I want to put it in the library, but would like to simplify the cache a bit before putting it in the library. Be aware that addons need their local version of this cache, otherwise they won't compile against previous versions of GRASS 7.
