/**
 * This extension is based off the {@link AMDDrawIndirectCount VK_AMD_draw_indirect_count} extension. This extension allows an application to source the number of draws for indirect draw calls from a buffer.
 * 
 * Applications might want to do culling on the GPU via a compute shader prior to drawing. This enables the application to generate an arbitrary number of drawing commands and execute them without host intervention.
 * 
 * Promotion to Vulkan 1.2
 * 
 * All functionality in this extension is included in core Vulkan 1.2, with the KHR suffix omitted. However, if Vulkan 1.2 is supported and this extension is not, the entry points {@link VK12#vkCmdDrawIndirectCount CmdDrawIndirectCount} and {@link VK12#vkCmdDrawIndexedIndirectCount CmdDrawIndexedIndirectCount} are optional. The original type, enum and command names are still available as aliases of the core functionality.
