    * Buffer views of all (valid) types and formats can be created from all (compatible) buffers
  + ** There are 2 buffer types and 173 different formats.
    * Various view sizes
    ** Complete buffer
    ** Partial buffer
    * View can be created before and after attaching memory to buffer
  + ** 2 tests for each bufferView
    * Changing memory binding makes memory contents visible in already created views
    ** Concurrently changing memory binding and creating views

   * All (valid and supported) combinations of create and usage flags work
   * Buffers of various sizes can be created and they report sensible memory requirements
   * Sparse buffers: very large (limit TBD) buffers can be created

  -------
  
  Buffers will have a lot of coverage from memory management and access tests. Targeted buffer tests need to verify that various corner-cases and more exotic configurations work as expected.
