B-splines are a special interpolating function which allows drawing smooth
curves. They can be drawn by QD II to extent that anything can be drawn by 
QD II by using _MoveTo and _LineTo. Basically, input to the spline function
is a set of control points. As the line is drawn, the line tends to head 
towards these pointes, but not necessarily pass through them.

Maybe I can throw something together over the weekend. Don't get over excited
though, it is not going to be very speedy. It will be sort of like 3-D graphics
on the GS. There are ways of doing it quickly, but not easily.
