The viewer node has been expanded to have a field input next to the geometry input. When both are connected (by ctrl+shift clicking on a node) the spreadsheet will show the evaluated field on the geometry. The operator to link to the viewer has become a bit smarter. It automatically detects if it should link to the geometry or field input. In the future some more smartness could be added, such as automatically relinking the "right" geometry when viewing a field. Internally, there are two major changes: * Refactor of what happens when ctrl+shift clicking on a node to link to a viewer. The behavior of the geometry nodes viewer is a bit more complex than that of the compositor viewers. The behavior in compositing nodes should not have changed. Any change should be reported as a bug (and then we can decide if it's worse than before or if it needs fixing). * Evaluation, display and caching of fields in the spreadsheet editor.
