 ** Enumeration tokens for SPIR-V, in various styles:
 **   C, C++, C++11, JSON, Lua, Python
-** 
+**
 ** - C will have tokens with a "Spv" prefix, e.g.: SpvSourceLanguageGLSL
 ** - C++ will have tokens in the "spv" name space, e.g.: spv::SourceLanguageGLSL
 ** - C++11 will use enum classes in the spv namespace, e.g.: spv::SourceLanguage::GLSL
 ** - Lua will use tables, e.g.: spv.SourceLanguage.GLSL
 ** - Python will use dictionaries, e.g.: spv['SourceLanguage']['GLSL']

 ** Some tokens act like mask values, which can be OR'd together,
 ** while others are mutually exclusive.  The mask-like ones have
 ** "Mask" in their name, and a parallel enum that has the shift
