  Use C++11 raw string literals instead of SHADER_SOURCE macro
  
  This is better in many ways:
  1. It doesn't confuse clang format
  2. \n doesn't need to be included after preprocessor directives like
     the version directive.
  3. It's using built-in functionality instead of something custom.
  
  Raw string literals should be the preferred way to include shader
  source in C++ files going forward.
