WIP Intro revamp

I'm well aware that the intro sequence is the weakest link in AV (probably resulting from how I rushed through it in order to make a festival deadline).  I'm in the progress of revamping it to be a bit more dynamic and show more relevant parts of Trace's past.  Here's one of the screens in progress.  The hill/mesa is largely placeholder.  The clouds need a bit of work.  I was more or less going to leave the rest as is.
