+/**
+ * Given three sequential points, p0, p1 and p2, find the left and right
+ * control points for p1.
+ *
+ * The three points are expected to have x and y properties.
+ *
+ * The alpha parameter controls the amount of smoothing.
+ * If α=0, then both control points will be the same as p1 (i.e. no smoothing).
+ *
+ * Returns [l1x, l1y, r1x, r1y]
+ *
+ * It's guaranteed that the line from (l1x, l1y)-(r1x, r1y) passes through p1.
+ * Unless allowFalseExtrema is set, then it's also guaranteed that:
+ *   l1y ∈ [p0.y, p1.y]
+ *   r1y ∈ [p1.y, p2.y]
+ *
+ * The basic algorithm is:
+ * 1. Put the control points l1 and r1 α of the way down (p0, p1) and (p1, p2).
+ * 2. Shift l1 and r2 so that the line l1–r1 passes through p1
+ * 3. Adjust to prevent false extrema while keeping p1 on the l1–r1 line.
+ *
+ * This is loosely based on the HighCharts algorithm.
