This extension is based off the VK_AMD_draw_indirect_count extension. This extension allows an application to source the number of draws for indirect drawing 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 vkCmdDrawIndirectCount and vkCmdDrawIndexedIndirectCount are optional. The original type, enum and command names are still available as aliases of the core functionality.

New Commands
