| === 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. |
