I have observed that this seems to be one of the most frequently asked 
questions on the list, aside from compilation / installation issues. It 
seems to trip up new users very frequently and I think its fair to say 
that that is because setting a circle symbol for a line is, at first 
glance, counterintuitive.

Has there ever been any consideration of the idea of making a circle 
symbol default when setting the thickness property of lines? That would 
make things more intuitive and more in line with the way other web 
mapping, GIS, and graphics packages work. In fact, Mapserver is the only 
application I've ever used in which you need to apply a symbol to a line 
to adjust its thickness. I guess there is a dependency on the symbol 
file, but could things be done in such a way that a circle symbol is 
available in the actual core of Mapserver and is used by default? Users 
could still override this if they choose to use a symbol, but if not 
they get the circle symbol and only have to use size to define the 
thickness of a line.

Thanks.
