/**
* This extension adds support for the following SPIR-V extension in Vulkan:
*
*
* - SPV_KHR_shader_ballot
*
*
* This extension provides the ability for a group of invocations, which execute in parallel, to do limited forms of cross-invocation communication via a group broadcast of a invocation value, or broadcast of a bitarray representing a predicate value from each invocation in the group.
*
* This extension provides access to a number of additional built-in shader variables in Vulkan:
*
*
* - {@code SubgroupEqMaskKHR}, which contains the subgroup mask of the current subgroup invocation,
* - {@code SubgroupGeMaskKHR}, which contains the subgroup mask of the invocations greater than or equal to the current invocation,
* - {@code SubgroupGtMaskKHR}, which contains the subgroup mask of the invocations greater than the current invocation,
* - {@code SubgroupLeMaskKHR}, which contains the subgroup mask of the invocations less than or equal to the current invocation,
* - {@code SubgroupLtMaskKHR}, which contains the subgroup mask of the invocations less than the current invocation,
* - {@code SubgroupLocalInvocationId}, which contains the index of an invocation within a subgroup, and
* - {@code SubgroupSize}, which contains the maximum number of invocations in a subgroup.
*
*
* Additionally, this extension provides access to the new SPIR-V instructions:
*
*
* - {@code OpSubgroupBallotKHR},
* - {@code OpSubgroupFirstInvocationKHR}, and
* - {@code OpSubgroupReadInvocationKHR},
*
*
* When using GLSL source-based shader languages, the following variables and shader functions from GL_ARB_shader_ballot can map to these SPIR-V built-in decorations and instructions:
*
*
* - {@code in uint64_t gl_SubGroupEqMaskARB;} → {@code SubgroupEqMaskKHR},
* - {@code in uint64_t gl_SubGroupGeMaskARB;} → {@code SubgroupGeMaskKHR},
* - {@code in uint64_t gl_SubGroupGtMaskARB;} → {@code SubgroupGtMaskKHR},
* - {@code in uint64_t gl_SubGroupLeMaskARB;} → {@code SubgroupLeMaskKHR},
* - {@code in uint64_t gl_SubGroupLtMaskARB;} → {@code SubgroupLtMaskKHR},
* - {@code in uint gl_SubGroupInvocationARB;} → {@code SubgroupLocalInvocationId},
* - {@code uniform uint gl_SubGroupSizeARB;} → {@code SubgroupSize},
* - {@code ballotARB}() → {@code OpSubgroupBallotKHR},
* - {@code readFirstInvocationARB}() → {@code OpSubgroupFirstInvocationKHR}, and
* - {@code readInvocationARB}() → {@code OpSubgroupReadInvocationKHR}.
