Vista and XP come with the capability of doing Bezier curves. that
came with NT if I remember right.
controlling Bezier curves is like Alice in Wonderland trying to use a
flamingo as a croquet mallet.
I'm not saying take bezier curves out, because paint programs and
people use them. I am saying "Add spline curves", such as Akima
Spline.
with splines you just pick the points along the curve you want, and it
fits the curve to those points. simple. only gotcha is that you need
extra points around sharp edges.
