// TranslatorMetal:
//   A GLSL-based translator that outputs shaders that fit GL_KHR_vulkan_glsl.
//   It takes into account some considerations for Metal backend also.
//   The shaders are then fed into glslang to spit out SPIR-V (libANGLE-side).
//   See: https://www.khronos.org/registry/vulkan/specs/misc/GL_KHR_vulkan_glsl.txt
//
//   The SPIR-V will then be translated to Metal Shading Language later in Metal backend.
