.. py:function:: create_event_val(tp: int, z: tuple[int], y: tuple[int], x: tuple[int], old_val: int, target_val: int) -> list[tuple[tuple[numpy.ndarray, numpy.ndarray, numpy.ndarray, numpy.ndarray], numpy.ndarray, int]]

   Create event values to simulate a paint event


.. py:function:: test_paint_event(make_napari_viewer, graph_3d, segmentation_3d)

   Test paint event processing

   1) Paint with a new label (4), new track id (4)
   2) Replace node 3 with new label 6, breaking edge (2,3), establishing edge (5,6)
   3) Erase part of node 6
   4) Undo erase event
