Open RV's PaintIPNode recompiles drawings when a pen/text/rect/line/arrow/ellipse/frame component changes and reads a fixed property list; uuid, softDeleted and undo/redo data are stored in the session but never read by this node, so they have no render effect here (deleted shapes disappear because they are left out of the order list).
