v1.3.16

rgl 1.3.16

Bug fixes

• triangulate() now uses the earcut library
  from https://github.com/mapbox/earcut.hpp, which
  should be faster and more reliable than the
  previous R implementation.
• In cases where the X11 server did not provide sufficient
  support, rgl.init() could sometimes segfault. That has
  been fixed, and warning messages have been made more
  informative.
