Comment (by mlennert):

 One related issue that should be dealt with ASAP: when doing proportionate
 symbols with size_column, the size parameter for symbols represents a
 scaling factor, not a size. However, d.legend.vect uses it as a size
 indicator meaning that when you set your scaling factor to a small value
 (values can easily close to zero, such as 0.001) the symbol in the legend
 also becomes very small.

 Probably the best solution would be to allow the use d.legend.vect's
 symbol_size also for symbols, maybe through a flag to d.legend.vect ("Use
 symbol_size also for point symbols").
