  -- == Description
  --
  -- This extension adds support for the following SPIR-V extension in
  -- Vulkan:
  --
  -- -   @SPV_NV_viewport_array2@
  --
  -- which allows a single primitive to be broadcast to multiple viewports
  -- and\/or multiple layers. A new shader built-in output @ViewportMaskNV@
  -- is provided, which allows a single primitive to be output to multiple
  -- viewports simultaneously. Also, a new SPIR-V decoration is added to
  -- control whether the effective viewport index is added into the variable
  -- decorated with the @Layer@ built-in decoration. These capabilities allow
  -- a single primitive to be output to multiple layers simultaneously.
  --
  -- This extension allows variables decorated with the @Layer@ and
  -- @ViewportIndex@ built-ins to be exported from vertex or tessellation
  -- shaders, using the @ShaderViewportIndexLayerNV@ capability.
  --
  -- This extension adds a new @ViewportMaskNV@ built-in decoration that is
  -- available for output variables in vertex, tessellation evaluation, and
  -- geometry shaders, and a new @ViewportRelativeNV@ decoration that can be
  -- added on variables decorated with @Layer@ when using the
  -- @ShaderViewportMaskNV@ capability.
  --
  -- When using GLSL source-based shading languages, the @gl_ViewportMask@[]
  -- built-in output variable and @viewport_relative@ layout qualifier from
  -- @GL_NV_viewport_array2@ map to the @ViewportMaskNV@ and
  -- @ViewportRelativeNV@ decorations, respectively. Behaviour is described
  -- in the @GL_NV_viewport_array2@ extension specification.
  --
  -- Note
  --
  -- The @ShaderViewportIndexLayerNV@ capability is equivalent to the
  -- @ShaderViewportIndexLayerEXT@ capability added by
  -- @VK_EXT_shader_viewport_index_layer@.
