/**
* Structure specifying a draw indirect 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 the “Vertex Input Description” section
* - If the drawIndirectFirstInstance feature is not enabled, {@code firstInstance} must be 0
*
*
* See Also
*
* {@link VK10#vkCmdDrawIndirect CmdDrawIndirect}
*
* Member documentation
*
*
* - {@code vertexCount} – the number of vertices to draw.
* - {@code instanceCount} – the number of instances to draw.
* - {@code firstVertex} – the index of the first vertex to draw.
* - {@code firstInstance} – the instance ID of the first instance to draw.
*
*
* Layout
*
* struct VkDrawIndirectCommand {
uint32_t vertexCount;
uint32_t instanceCount;
uint32_t firstVertex;
uint32_t firstInstance;
