=== Description

This extension adds support for the SPIR-V extension
`SPV_EXT_shader_stencil_export`, providing a mechanism whereby a shader may
generate the stencil reference value per invocation.
When stencil testing is enabled, this allows the test to be performed
against the value generated in the shader.
