glad to hear it works as expected. Just want to add that the programmer's route,
aka doing it by the math, is quite viable, too. Some selected options:

- the MathMap plugin probably enables the most concise solution:
  http://www.complang.tuwien.ac.at/schani/mathmap/

- with knowledge in C, it's not a big step to prototype using either
  Lua (the gluas plugin) or the built-in python-fu.

- a plain C plugin gives the best processing speed at the price of the
  slowest development cycle.

New contributors are always welcome! There are plenty of opportunities
to help the project, by far it's not just about coding [1].
And posing useful problems here is already helpful, too.
Of course, donations are always welcome [2].
