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 #gpu::Batch 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.
