[R-SIG-Mac] quartz and pch=0

[Chabot Denis]

Hi,

I don't know when this started, but it is relatively recent, i.e.  
must have happened less than one year ago:

data points plotted with pch=0 do not have a uniform size or shape.  
For instance:

plot(1:20, pch=0)

If I save the plot to pdf, the non-uniform plot symbols remain. If I  
plot with pdf device, all data points have exactly the same shape and  
size. I am pretty sure this used to be the case with quartz as well.

Is it just me?
