Description
Created attachment 336624 Adds the first version of user's pictures getters
This adds functions for getting user's avatar. The function basically returns GBytes, so the actual interpretation is left to the user. The contents are usually some JPEG or PNG data.
For that I had to modify the build system to add the generation of functions that register the enum type.
