I recently purchased a Wacom tablet, and would like to draw vector art with it. The type of functionality I am looking for is a program that is able to recognize "fuzzy" shapes. i.e. if I draw something that looks like an ellipse, I would like the program to turn that into a perfect ellipse. If I draw something that looks like a line segment, it should be converted into a straight line segment. Has anyone heard of anything like this?
