Sorry, I was a bit quick, but I actually meant that we need a specification
to work with.  That is not usually as simple as just a mathematical formula,
anyway I didn't meant to make the conversation too heavy, either.

That said, I will look into the code when I find some time: might be
already correct mathematically, but it is very heavy on the CPU.

Sorry again, it seems to work fine, actually.  Here is the screenshot of a
run, where I have let it run for 1 minute, then I have added 4 points and
let it run for 5 more minutes (then stopped as my CPU was over-heating:-):

I am on a high-end laptop with an AMD Radeon on board, nothing more than
that.  The browser is not taking advantage of the AMD GPU anyway, but
right away I wouldn't know how to improve on that (or maybe force the
canvas to use the GPU?).  To be investigated...
