/**
* This extension adds support for the following SPIR-V extension in Vulkan:
*
*
* - {@code SPV_KHR_shader_draw_parameters}
*
*
* The extension provides access to three additional built-in shader variables in Vulkan:
*
*
* - {@code BaseInstance}, which contains the {@code firstInstance} parameter passed to drawing commands,
* - {@code BaseVertex}, which contains the {@code firstVertex} or {@code vertexOffset} parameter passed to drawing commands, and
* - {@code DrawIndex}, which contains the index of the draw call currently being processed from an indirect draw call.
*
*
* When using GLSL source-based shader languages, the following variables from {@code GL_ARB_shader_draw_parameters} can map to these SPIR-V built-in decorations:
*
*
* - {@code in int gl_BaseInstanceARB;} → {@code BaseInstance},
* - {@code in int gl_BaseVertexARB;} → {@code BaseVertex}, and
* - {@code in int gl_DrawIDARB;} → {@code DrawIndex}.
*
*
* Promotion to Vulkan 1.1
*
* All functionality in this extension is included in core Vulkan 1.1, however a feature bit was added to distinguish whether it is actually available or not.
