[bug?] request_extra_fileinfo_start/_end load order is reversed

[donotbugme]

When I set request_extra_fileinfo_start and request_extra_fileinfo_end to a large number so it preloads thumbnails around my position, and I scroll to a part of the list that has a chunk of unloaded thumbnails, it loads the furthest ones first and the ones just outside my view last.

[void]

I will look into loading the visible thumbnails first.

For now, please set request_extra_fileinfo_start to 0 or a small number.
