There is Bloc, which is a fully vector based engine that is resolution independent (actually there is Sparta under this which is a recast of Athens).

All tools can use it but are not part of the official Pharo6 release. This does not mean that Bloc doesn't work.

On top of Bloc is Brick, with the widgets.

This project is meant to have Pharo support whatever surface and resolution one is throwing at it. There are commercial projects underway using it for tabletop style UIs.

So, all of Moz2D style stuff is working in Bloc
