  Print stack backtrace on critical failure.
  
  We reuse code from Skia to walk the stack on Posix platforms. See:
  https://github.com/google/skia/blob/master/tools/CrashHandler.cpp
  
  On Windows we use a BSD-licensed tool called StackWalker. See:
  https://github.com/JochenKalmbach/StackWalker
  
  This allows us to get high quality stack traces on Win/Linux/Mac.
