Yes, it eats a lot of memory.

Wasn't this question discussion during the OpenGL driver? It is a bit 
similar (colors for vertices). Aha, not the question here, since we are in 
2D projections, not in 3D coordinats.

It would need to add
 	float r,g,b;
into the definition of gpiPoint.

Then there are these possibilities:
1. Add also
 	int fade_color
    into gpiPoint. Then
 	void XX_filled_polygon (int points, gpiPoint *corners)
    won't change. 
2. Change
         void XX_filled_polygon (int points, gpiPoint *corners, t_fade *fade)
    The last new param will be ignored by most terminals.
3. As term->set_color() is called before each term->filled_polygon(),
    the fading option could be passed at this point.

It is probably not difficult to implement. You can have a nice play.
