In scatter mode a two-array (X/Y) plot rebuilt the table and chart once per property setter (data, offset, stride) and restyled every marker four times, so a ~4000-point phase portrait froze for ~0.8s per refresh. - SeerArrayWidget: add a BulkUpdate RAII guard that defers create() until a burst of setters completes, so a refresh does one rebuild, not several. - redecorateScatterSeries: drop the two redundant transparent passes; after addSeries() the series holds the theme pen/brush, so setPen(NoPen)/ setBrush() are already real transitions and either re-pushes both to the markers. ~800ms -> ~200ms per refresh at 4000 points; line/spline and marker appearance unchanged. Add tests/helloscatter, a 4000-point two-array phase portrait with a breakpoint loop, to reproduce the slow refresh.
