*
* When a photo was uploaded into the message using the (profile wall) ajax
* uploader, The permissions are initially set to disallow anybody but the
* owner from seeing it. This is because the permissions may not yet have been
* set for the post. If it's private, the photo permissions should be set
* appropriately. But we didn't know the final permissions on the post until
* now. So now we'll look for links of uploaded photos and attachments that are in the
* post and set them to the same permissions as the post itself.
*
* If the post was end-to-end encrypted we can't find images and attachments in the body,
* use our media_str input instead which only contains these elements - but only do this
* when encrypted content exists because the photo/attachment may have been removed from
* the post and we should keep it private. If it's encrypted we have no way of knowing
* so we'll set the permissions regardless and realise that the media may not be
* referenced in the post.
*
* What is preventing us from being able to upload photos into comments is dealing with
* the photo and attachment permissions, since we don't always know who was in the
* distribution for the top level post.
*
* We might be able to provide this functionality with a lot of fiddling:
* - if the top level post is public (make the photo public)
* - if the top level post was written by us or a wall post that belongs to us (match the top level post)
* - if the top level post has privacy mentions, add those to the permissions.
* - otherwise disallow the photo *or* make the photo public. This is the part that gets messy.

*
* When a photo was uploaded into the message using the (profile wall) ajax
* uploader, The permissions are initially set to disallow anybody but the
* owner from seeing it. This is because the permissions may not yet have been
* set for the post. If it's private, the photo permissions should be set
* appropriately. But we didn't know the final permissions on the post until
* now. So now we'll look for links of uploaded photos and attachments that are in the
* post and set them to the same permissions as the post itself.
*
* If the post was end-to-end encrypted we can't find images and attachments in the body,
* use our media_str input instead which only contains these elements - but only do this
* when encrypted content exists because the photo/attachment may have been removed from
* the post and we should keep it private. If it's encrypted we have no way of knowing
* so we'll set the permissions regardless and realise that the media may not be
* referenced in the post.
*
* What is preventing us from being able to upload photos into comments is dealing with
* the photo and attachment permissions, since we don't always know who was in the
* distribution for the top level post.
*
* We might be able to provide this functionality with a lot of fiddling:
* - if the top level post is public (make the photo public)
* - if the top level post was written by us or a wall post that belongs to us (match the top level post)
* - if the top level post has privacy mentions, add those to the permissions.
* - otherwise disallow the photo *or* make the photo public. This is the part that gets messy.
