Each texture made (with how its content started), uploaded, uploaded again, released, taken back or destroyed is one line with its frame, address, format, size, layers and flags, so a one-frame flicker in the thumbnails can be matched to the textures of that frame. events.tsv is written first: the thumbnails take about five seconds, and a game closed meanwhile kept no frames.tsv.
