I see many people use "rotatewithview" for hotspots placed at the nadir. However, whether I set it true or false, it does not change a thing, the hotspot keeps rotating :(
I figured it out, it seems to be a bug (or at least an undocumented feature):
When distorted= "true", then "rotatewithview" and "crop" are ignored (possibly even more properties, but these are the ones that had me looking for quite a while).
Update: now that I started searching in the forum for "distorted", I saw that many people have had this problem, but that was only after I figured that "distorted" was the source of my troubles
