Summary: Won't make things go much faster since everything that was being passed by value is refcounted but still const & is a bit faster than refcounting For shared pointers instead of adding const & we move them into the destination variable saving some cpu usage but at the same time making clear the pointer is being stored by not being const & Reviewers: zzag Reviewed By: zzag Subscribers: zzag, kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D25022
