Passes an 'index' magic number to the upload/save functions which
pass that back to the *Done callbacks, so we know if the *raw*
snapshot is still up to date when the upload succeeds or fails.
Fix CMakeLists being out of order.
Add setting SnapshotFeedAddLocation to keep track of user's preference whether or not to include location in uploads to profile feed.
Clean up LLFloaterFeed to take only what it needs, also gave it a boost~
Remove saveFeed() from LLFloaterSnapshot, removing the dependency on LLWebProfile.
Compile fixes for LLFloaterSnapshot.
Prettied up the upload to feed floater.
TODO: Does Location even work? I can't get it to appear, never seems to get used right in v-d either.
This is just a skeleton, roughly copied from the Postcoard
code, which is very similar. Nothing in indra/newview/llfloaterfeed.cpp
has been changed yet, apart from a few deletions (to make it compile)
and the literal replacement of "Postcard" with "Feed".
indra/newview/llfloatersnapshot.cpp was updated however to
open the new floater when one tries to upload a snapshot to the feed.
It is still needed to make a callback to saveFeed(), or rather to
move that function to the saveFeed that is in llfloatersnapshot.cpp.
