I do that in 4.0, without classitems (i mentioned that because 
Fresio seemed to not understand well the layer and class model), just 
creating new classobj's and styleobj's, as i wrote in the modified code 
example, that is, creating new classes for each point that must be drawn
differently.

I never did the dynamic drawing with only one class (in 3.6 i also added
new classes), maybe with the addition of the styleObj the way the points 
are drawn changed and they now respect the one class per way of drawing 
'rule' :), maybe Daniel or Steve can enlighten us on this issue.
