    Creating a session saves the canvas's active tool, pushes a
    OpenSWMMVisMapToolPickNode and forwards its picks; finishing (or
    destroying) the session restores the previous tool. The consumer
    decides what to do with a pick — reject an ineligible node and keep
    waiting, or accept it and finish(). Switching to another canvas tool
    while the session is active counts as a cancel.

    Parent the session to whatever must outlive the wait: a non-modal
    dialog, or — for a property-grid cell editor, which the grid closes
    the moment the map takes focus — the layer itself, with the result
    written through the layer rather than through the editor.
