Detailed Description

A container to store instance state for a drawitem.

During culling, the visibility state will be set. If the instance has a batch, the batch will get a DrawItemInstanceChanged callback.

The Batch is responsible for calling SetBatch and SetBatchIndex when adding / appending the instance. If the batch does not require the DrawItemInstanceChanged callback, then this step can be skipped
