Infinite loop from triangulatePolygon2

[joshuahhh]

The following code hangs in an infinite loop:

const cga = require("cga")
cga.triangulatePolygon2([[392,114],[216,179],[159,295],[215,267]])

As far as I know, this is a pretty normal polygon:

I'm not sure what's going on.

The problem is that the ears array is all false. Reversing the order of the vertices makes the function work. I guess that means cga requires a certain orientation for the polygon.
