Description
The members of VkTraceRaysIndirectCommand2KHR have the same meaning as
the similarly named parameters of vkCmdTraceRaysKHR.
Indirect shader binding table buffer parameters must satisfy the same memory alignment and binding requirements as their counterparts in vkCmdTraceRaysIndirectKHR and vkCmdTraceRaysKHR.
