Dissecting GstSegments

During all these years using GStreamer, I’ve been having to deal with GstSegments in many situations. I’ve always have had an intuitive understanding of the meaning of each field, but never had the time to properly write a good reference explanation for myself, ready to be checked at those times when the task at hand stops being so intuitive and nuisances start being important. I used the notes I took during an interesting conversation with Alba and Alicia about those nuisances, during the GStreamer Hackfest in A Coruña, as the seed that evolved into this post.
