* B-Splines curves & NURBS

* Code in Pen2D Logo's rendering functions (such as av,re,td,tg,mv, ...) 

* no translation available until I understand the french version !!!!

* Scale of the dot clouds

* cloud dots interpolation

* Isocurves (f(x,y) = cte ) rendering

* To code  y=a*exp(bx); y=a * x^b; y = a + b ln(x) curves.

* Display the coordinate systems

* Display the objects when they ares selected or highlighted

* Fractal objects generate by a pattern and plane's transformations

* Create pattern classes (points, triangles, squares, diamants,...) to accelerate the rendering process of functions and dot clouds instead of writing if...then...else statements in the draw method.

* Optimize in the parser,  functions (cartesian, polar or parametric) values computation in order to compute  all the values' table at once.
