+// medians of the spherical triangle. It is possible to show that this

+// area), the result equals the centroid of the original triangle. This is
+// not true of the other centroids.
+//
+// Also note that the surface centroid may be nowhere near the intuitive
+// "center" of a spherical triangle. For example, consider the triangle
+// with vertices A=(1,eps,0), B=(0,0,1), C=(-1,eps,0) (a quarter-sphere).

+// (the segment connecting A to the midpoint of BC) passes through S, since
