----------
* Nueva funcion en la graphics.dll: get_rgb(color,&r,&g,&b). obtiene las
componentes RGB de un color dado. naturalmente es similar a la funcion
homonima que hice en su dia para div2 ;) ojo, no esta preparada para
8 bpp (en esta profundidad debera devolver valores de 0..63, ademas de
diferenciar la paleta activa de la paleta cargada) (Er_Makina)
