I renamed the chord length and ray length queries and changed the names
of the curves they generated in the ultra file. Specifically, the new
names of the queries are:

     Chord Length Distribution - individual
     Chord Length Distribution - aggregate
     Ray Length Distribution - individual
     Ray Length Distribution - aggregate

I also updated the regression suite to match the changes and changed the
baseline images of images that changed (the labels on the curves changed).
