It's easy to make chart.Weights a generic, but it will be much harder 
with chart.Scatter.*

Because Performanceanalytics is on CRAN and much more widely used, we'd 
need to match the argument list, and create a chart.Scatter.default in 
PerfA.  I don't see any way to match the argument list though.
