Detailed Description

DRW Instance Data Manager This is a special memory manager that keeps memory blocks ready to send as VBO data in one continuous allocation. This way we avoid feeding GPUBatch each instance data one by one and unnecessary memcpy. Since we lose which memory block was used each DRWShadingGroup we need to redistribute them in the same order/size to avoid to realloc each frame. This is why #DRWInstanceDatas are sorted in a list for each different data size.
