generational structure of arrays, AKA slotmaps
- Important bit is that the components of each type are all in contiguous memory
- Core reference counted mapping, followed by dependent mappings for each
  component type

  - In pim, the current component types are:
    - Mesh
    - Texture -or- TexTable

  - Appear to be two separate similar systems.
    - First is containers/table.h, used in the non-vulkan renderer
      - This has ref counting and is the first level. If no existing item
        found, it calls into vkrTexTable which then uses IdAlloc.

    - IdAlloc is used for vulkan stuff and also for some
      quake-specific stuff?
        - IdAlloc does not have reference counting.

  - IdAlloc: 
    - IdAlloc_Alloc to get GenId. the data is passed to this and is allocated
      to the correct size.

  - Going to work based on the assumption that reference counting won't hurt
    to add. Can make it optional and probably will be fine.
