Add a "draw procedural geometry" command.
When the command buffer executes, this will do a draw call on the GPU, without any vertex or index buffers. This is only useful on DirectX 11 level hardware where shaders can read arbitrary data from ComputeBuffer buffers.
In the vertex shader, you'd typically use SV_VertexID and SV_InstanceID input variables to fetch data from some buffers.
