/**
 * This extension adds support for the following SPIR-V extension in Vulkan:
 * 
 * 
 * {@code SPV_NV_fragment_shader_barycentric}
 * 
 * 
 * The extension provides access to three additional fragment shader variable decorations in SPIR-V:
 * 
 * 
 * {@code PerVertexNV}, which indicates that a fragment shader input will not have interpolated values, but instead must be accessed with an extra array index that identifies one of the vertices of the primitive producing the fragment
 * {@code BaryCoordNV}, which indicates that the variable is a three-component floating-point vector holding barycentric weights for the fragment produced using perspective interpolation
 * {@code BaryCoordNoPerspNV}, which indicates that the variable is a three-component floating-point vector holding barycentric weights for the fragment produced using linear interpolation
 * 
 * 
 * When using GLSL source-based shader languages, the following variables from {@code GL_NV_fragment_shader_barycentric} maps to these SPIR-V built-in decorations:
 * 
 * 
 * {@code in vec3 gl_BaryCoordNV;} → {@code BaryCoordNV}
 * {@code in vec3 gl_BaryCoordNoPerspNV;} → {@code BaryCoordNoPerspNV}
 * 
 * 
 * GLSL variables declared using the {@code __pervertexNV} GLSL qualifier are expected to be decorated with {@code PerVertexNV} in SPIR-V.
