Migrate demo artwork and fix all failing CI tests (#1459)

* Initial work on fixing tests

* Fix formatting

* Remove dead code to satisfy rustc warnings

* Insert into an artboard

* Load updated artwork in editor

* Remove popup when importing image

* Fix up demo art

* Change transform app[lication method

* Reduce number of enums called BlendMode

* Finalize the demo artwork upgrade

* Code review pass
