--
-- == Description
--
-- This extension adds support for the following SPIR-V extension in
-- Vulkan:
--
-- -   @SPV_NV_sample_mask_override_coverage@
--
-- The extension provides access to the @OverrideCoverageNV@ decoration
-- under the @SampleMaskOverrideCoverageNV@ capability. Adding this
-- decoration to a variable with the
-- 'Vulkan.Core10.FundamentalTypes.SampleMask' builtin decoration allows
-- the shader to modify the coverage mask and affect which samples are used
-- to process the fragment.
--
-- When using GLSL source-based shader languages, the @override_coverage@
-- layout qualifier from @GL_NV_sample_mask_override_coverage@ maps to the
-- @OverrideCoverageNV@ decoration. To use the @override_coverage@ layout
-- qualifier in GLSL the @GL_NV_sample_mask_override_coverage@ extension
-- must be enabled. Behavior is described in the
-- @GL_NV_sample_mask_override_coverage@ extension spec.
