A new system variable is added: @BNLP .It controls the auto-nested layout percent of bubble size. The default value is 20, which means when the bubble scale is larger than 20% of the whole layer in size, its layout will be switched to Nested from Linear if you renew/add a bubble scale for a size-indexed scatter/line+symbol plot.
