* Google changed from an Inc to an LLC.
This happened back in 2017 but we didn’t notice. Officially we should update files from Inc to LLC when they are changed as part of regular edits, but this is a nightmare to remember for the next decade.
* Remove project description/titles from licenses
This is no longer part of Google’s header requirements. Our existing descriptions were useless (“Visual Blocks Editor”) or grossly obselete (“Visual Blocks Language”).
* License no longer requires URL.
* Fix license regexps.
Previously it returned x,y,width,height. Returning top,bottom,left,right results in simpler code, both in this function and in downstream callers.
This commit makes the minumum change to the metrics_test. I’m happy to change the test’s data if that makes more sense.
