-- == Description
--
-- This extension adds Vulkan support for the
-- <https://htmlpreview.github.io/?https://github.com/KhronosGroup/SPIRV-Registry/blob/master/extensions/KHR/SPV_KHR_terminate_invocation.html SPV_KHR_terminate_invocation>
-- SPIR-V extension. That SPIR-V extension provides a new instruction,
-- @OpTerminateInvocation@, which causes a shader invocation to immediately
-- terminate and sets the coverage of shaded samples to @0@; only
-- previously executed instructions will have observable effects. The
-- @OpTerminateInvocation@ instruction, along with the
-- @OpDemoteToHelperInvocation@ instruction from the
-- <VK_EXT_shader_demote_to_helper_invocation.html VK_EXT_shader_demote_to_helper_invocation>
-- extension, together replace the @OpKill@ instruction, which could behave
-- like either of these instructions. @OpTerminateInvocation@ provides the
-- behavior required by the GLSL @discard@ statement, and should be used
-- when available by GLSL compilers and applications that need the GLSL
-- @discard@ behavior.
