/**
 * This extension adds support for the {@code ShaderViewportIndexLayerEXT} capability from the {@code SPV_EXT_shader_viewport_index_layer} extension in Vulkan.
 * 
 * This extension allows variables decorated with the {@code Layer} and {@code ViewportIndex} built-ins to be exported from vertex or tessellation shaders, using the {@code ShaderViewportIndexLayerEXT} capability.
 * 
 * When using GLSL source-based shading languages, the {@code gl_ViewportIndex} and {@code gl_Layer} built-in variables map to the SPIR-V {@code ViewportIndex} and {@code Layer} built-in decorations, respectively. Behaviour of these variables is extended as described in the {@code GL_ARB_shader_viewport_layer_array} (or the precursor {@code GL_AMD_vertex_shader_layer}, {@code GL_AMD_vertex_shader_viewport_index}, and {@code GL_NV_viewport_array2} extensions).
 * 
 * Note
 * 
 * The {@code ShaderViewportIndexLayerEXT} capability is equivalent to the {@code ShaderViewportIndexLayerNV} capability added by {@link NVViewportArray2 VK_NV_viewport_array2}.
 * 
 * 
 * Promotion to Vulkan 1.2
 * 
 * All functionality in this extension is included in core Vulkan 1.2.
 * 
 * The single {@code ShaderViewportIndexLayerEXT} capability from the {@code SPV_EXT_shader_viewport_index_layer} extension is replaced by the {@code ShaderViewportIndex} and {@code ShaderLayer} capabilities from SPIR-V 1.5 which are enabled by the shaderOutputViewportIndex and shaderOutputLayer features, respectively. Additionally, if Vulkan 1.2 is supported but this extension is not, these capabilities are optional.
 * 
 * Enabling both features is equivalent to enabling the {@code VK_EXT_shader_viewport_index_layer} extension.
