> That is true, it was part of the event recorder branch and it's used in these places. So we have code that creates thumbnails for saved games (in thumbnail_intern.cpp) and code that creates thumbnails for the event recorder.

In fact I think it was coming from Sword25 and then was also used in the event recorder. But that all doesn't really matter. The placement is odd and I wasn't happy with it in the first place when we merged that branch either. We can think of moving it to surface.[h/cpp] but that's not too important for this here.
