// 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:
// The SPIR-V will then be translated to Metal Shading Language later in Metal backend.
