In NodeTypes 'multipie' (and maybe other places)
the line
var polar = new Polar(polarNode.rho, begin);
must be changed to
var polar = new Polar(begin, polarNode.rho);
as Polar is defined as follows:
var Polar = function(theta, rho)
The bug has currently little effect, because the fill() is still working properly. But if one wants to draw lines instead of fill the bug becomes visible
