Title: Fix: Set offset_changed to FALSE after rendering

Before that patch, the logic is:

gboolean offset_changed = FALSE;
offset_changed = lib->offset_changed;
/* check if offset was changed and we need to prefetch thumbs */
if (offset_changed)
{
...
}

But lib->offset_changed was never set to FALSE once it became true. This patch sets it to FALSE after rendering once.
