  -The low-level alternative to [GPURayTracingAccelerationInstanceDescriptor](#GPURayTracingAccelerationInstanceDescriptor).
  -
  -This should be used when large amounts of data get used, or an instance has to be updated (e.g. it's transform) at some point. Note that there are no checks done for the data inside the buffer.
  -
  -The instance buffer wraps contiguous instances, where each instance entry is 64 bytes in size.

  -An instance entry within the instance buffer has the following layout:
  -
  -| Name | Size | Description
  -| :--- | :--- | :--- |
  -| transform | 48 Byte | 3x4 row-major transform matrix
  -| instanceId | 24 Bit | Can be used to provide arbitrary data to the Hit shaders.
  -| mask | 8 Bit | Ignore mask (see `traceNV`)
  -| instanceOffset | 24 Bit | Unused yet
  -| flags | 8 Bit | Flags for this instance (see [GPURayTracingAccelerationInstanceFlag](#GPURayTracingAccelerationInstanceFlag))
  -| accelerationContainerHandle | 8 Byte | Geometry container to be used by this instance. See [GPURayTracingAccelerationContainer.getHandle](#GPURayTracingAccelerationContainer)
