Also update the add-bounds script to also
rename files

This also includes new scripts for generating some data -- but I am going
to migrate the actual generator scripts to another repo soon

This one doesn't require autotracing the lines, which should make

Also adds the scripts used to generate them.

values where needed and removes the Firefox check from the click
detection code, so it works properly (and screenshots are fixed, too).
