  * src/base/ftoutln.c (FT_Outline_Reverse): Anchor first contour points.
  
  A cubic contour has to always start from an on-point. Therefore, we
  should not swap the first with the last point, which might be off, and
  obtain an invalid contour. This does not matter for conic contours.
  If anything, it also saves one swap there. Fixes #1207.
