/**
 * Native bindings to the KHR_shader_subgroup extension.
 * 
 * This extension enables support for the {@code KHR_shader_subgroup} shading language extension in OpenGL ES.
 * 
 * The extension adds API queries to be able to query
 * 
 * 
 * the size of subgroups in this implementation ({@link #GL_SUBGROUP_SIZE_KHR SUBGROUP_SIZE_KHR})
 * which shader stages support subgroup operations ({@link #GL_SUBGROUP_SUPPORTED_STAGES_KHR SUBGROUP_SUPPORTED_STAGES_KHR})
 * which subgroup features are supported ({@link #GL_SUBGROUP_SUPPORTED_FEATURES_KHR SUBGROUP_SUPPORTED_FEATURES_KHR})
 * whether quad subgroup operations are supported in all stages supporting subgroup operations ({@link #GL_SUBGROUP_QUAD_ALL_STAGES_KHR SUBGROUP_QUAD_ALL_STAGES_KHR})
 * 
 * 
 * In OpenGL ES implementations, this extension does NOT add support for SPIR-V or for any of the built-in shading language functions (8.18) that have
 * {@code genDType} (double) prototypes.
 * 
 * Requires {@link GLES31 GLES 3.1}.
