Rather than adding new term APIs again, which one of the current is already 
similar? I think that is XX_linewidth(), which changes line width for the 
current path. Thus if it is changed to
 	XX->linewidth(double lw, t_linetype_opts *opts)

then you could change whichever line properties you want. (Now you can think 
how to draw a line with a fading color :-)
