[GRASS5] D_color

[Jachym Cepicky]

Hallo developers,
according to d.vect.thematic, I try to modify d.legend slightly, so it is
useable for vector maps too.

Now I created structure 

struct vector_color {   /* color of vector files */
            char *vcat;
            int red;
            int blue;
            int green;
        } vcolors[100];

which is able to save color values in R:G:B and category value for 100
categories in the vector file.

d.legend uses

    int D_color(int color)

but how to set the (int color) value for it from R:G:B colors?

I don't know, if I can make d.legend work with vector files, but I try it :-)
