There's a long standing feature request of having a 2d drag, similar to the one we have for 1d Modifier.draggable.

Right now people use their own version using lower level building blocks, but a few features will be missing in their code: InteractionSource support or mutex-based priority dragging being a few to mention.

We need to expose the right building blocks for easy wiring or provide a ready to use modifier for such cases. Seems like this issue might be a good foundation for 2d scroll as well (b/214410040).

Over to Levi to start building up his backlog, but feel free to reassign to me or foundation alias if there are any questions or concerns.
