-       // The goal in this function is to replicate the exact behavior that was in the original
-       // BaseWindingForPlane() function (see below).  The only thing we're going to change is the
-       // accuracy of the operation.  The original code gave a preference for the vup vector to start
-       // out as (0, 0, 1), unless the normal had a dominant Z value, in which case vup started out
-       // as (1, 0, 0).  After that, vup was "bent" [along the plane defined by normal and vup] to
-       // become perpendicular to normal.  After that the vright vector was computed as the cross
-       // product of vup and normal.
-
-       // Once these vectors are calculated, I'm constructing the winding points in exactly the same
-       // way as was done in the original function.  Orientation is the same.
-
-       // Note that the 4 points in the returned winding_t may actually not be necessary (3 might
-       // be enough).  However, I want to minimize the chance of ANY bugs popping up due to any
-       // change in behavior of this function.  Therefore, behavior stays exactly the same, except
-       // for precision of math.  Performance might be better in the new function as well.
