polygon winding order

[mattdesl]

I'm trying to use this with polygons to determine the winding order. However, it seems to be suited for a small number of points (triangles and such mostly?).

In Chrome, the following with a larger set of points (e.g. 20+) tends to crash the browser:

var orientation = require('robust-orientation')
orientation.apply(orientation, path)

Is there a module better suited for this?

This computes the orientation of d+1 points in d dimensions. For a polygon, you would need to integrate over each triangle and then test the sum of all the areas to get the orientation.
