Certain use cases for multiview have a need for specifying a separate viewport and scissor for each view, without using shader-based viewport indexing as introduced with VK_EXT_shader_viewport_index_layer.

This extension adds a new way to control ViewportIndex with multiview. When the multiviewPerViewViewports feature is enabled and if the last pre-rasterization shader entry point’s interface does not use the ViewportIndex built-in decoration, then each view of a multiview render pass instance will use a viewport and scissor index equal to the ViewIndex.
