[Patch] add option to d.vect to make symbol size proportionate to square root of size_column
|Reported by:||mlennert||Owned by:|
The attached patch adds a flag to d.vect to use the square root of the size_column values. This allows to make the surface of circles instead of their heights proportionate to the size value.
I did not want to commit immediately as I saw that Hamish was working on d.vect. BTW thanks for allowing to scale the size_column value.
