TSdlGpuIndirectDrawCommand

A record specifying the parameters of an indirect draw command.

Note that the FirstVertex and FirstInstance fields are NOT compatible with built-in vertex/instance ID variables in shaders (for example, SV_VertexID); GPU APIs and shader languages do not define these built-in variables consistently, so if your shader depends on them, the only way to keep behavior consistent and portable is to always pass 0 for the correlating parameter in the draw calls.
