| Hello all,
| 
| I have two new graphic functions implemented: ribbon and spinmap.
| 
| 
| Examples
| * ribbon:
| 
| [x,y,Z] = sombrero;
| [X,Y] = meshgrid(x,y);
| ribbon(Y,Z);
| 
| 
| * spinmap:
| 
| image;spinmap
| 
| For more complex graphics like surf(peaks) spinmap is not very fast, but
| might be useful nevertheless.
