Donut Symbol.

[Bob Basques]

Does anyone know of a good way to make a donut symbol.

I need to be able to resize a symbol that is basically a donut.  Where 
the donut part is semi-opaque, and the center is open.  It's basically a 
min/max distance from a point overlay.  I have the dynamic handing off 
of the sizing handled already, but haven't figured out a good way to 
make a filled donut symbol.

I did mange to make a stacked symbol, but I would really like to have 
the center no be filled in, only the area between the MIN/MAX distance 
from the point picked.

Thanks
