I'm worried about curves consisting of millions of points. They need to 
be mapped to target coordinates and painted afterwords each time the plot 
needs to be refreshed. Is it possible to pass these points via an HTML 
based API with an acceptable performance ?

And what about oscilloscopes ( a common use case of QwtPlot ), that can 
only be implemented in an acceptable performance today with painting 
incrementally ( painting new points on top instead of repainting 
everything from scratch ) ?

I checked a Qt 4.8 snapshot, but was not able to identify what example it 
is ?
