Thanks for the answers!

And the result of a raster job is then coordinates in the Atlas?

Makes sense

It's not exactly an atlas then is it :P. Sorry if I wasn't clear; I was trying to understand whether the library or the application is managing the Atlas. Sounds like the library.

Yes.

The library manages the atlas, because it uses a particular packing algorithm that maximizes the performance of the accumulation step (by increasing parallelism) when rasterizing many glyphs at once.
