 #!CommitTicketReference repository="" revision="58997"
 Administration: Remove old IE9 code from `wp-admin/js/svg-painter.js`.

 About half of the file's code was a back-compat polyfill of base64
 functions for IE9.

 Since WordPress no longer supports IE9 as of version 4.8, and all modern
 browsers come with these functions, the polyfills can be removed.

 Follow-up to [26072], [26131], [26601], [47771].

 Props TobiasBg, sabernhardt.
 Fixes #61995.
