/**
* Structure specifying a indirect drawing command.
*
* Description
*
* The members of {@link VkDrawIndirectCommand} have the same meaning as the similarly named parameters of {@link VK10#vkCmdDraw CmdDraw}.
*
* Valid Usage
*
*
* - For a given vertex buffer binding, any attribute data fetched must be entirely contained within the corresponding vertex buffer binding, as described in Vertex Input Description
* - If the drawIndirectFirstInstance feature is not enabled, {@code firstInstance} must be 0
*
*
* See Also
*
* {@link VK10#vkCmdDrawIndirect CmdDrawIndirect}
*
* Layout
*
*
* struct VkDrawIndirectCommand {
* uint32_t {@link #vertexCount};
* uint32_t {@link #instanceCount};
* uint32_t {@link #firstVertex};
* uint32_t {@link #firstInstance};
