Comment (by mlennert):

 Replying to [comment:1 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").

 I've added a patch to show what I mean, but I'm acting a bit blindly,
 here, for lack of thorough understanding of d.legend.vect, so this
 definitely needs to be checked.
