Another compacts visible instance identifiers or draw commands into an output buffer and generates a count. Compaction adds bookkeeping but avoids processing empty entries. Group commands by the state that the chosen indirect mechanism can share; an arbitrary material or pipeline change is not automatically encoded by an ordinary draw command.
