The options from @Code "weight" downwards are also the complete
set of options of the @Code "@Slice" symbol.  The value of an
option is the value given at the @Code "@Slice" symbol, if any;
otherwise, the value at the enclosing @Code "@Pie" is used
if any; if it is not given there, the setup file value is used.
