Parametric is better

Now any vector represented curve can have a pattern based border.

But it's not all: the algorithm is robust enough to accept a parametric pattern. There is no restriction about combining short and/or long "dots" and "dashes". It can be so complicated as desired.

I'm planning a yet more powerful kind of parametrisation for curves drawing. Let's see if I can implement the model.

Someday I will see the raster and vector based tools working together in an unique nice software.
