// The metadata (ID, format, dimensions, number of planes, and plane
// stride/offset) of a FakeImage is immutable. The accessors for such metadata
// are thread-safe. The contents of the backing FakeBuffer object are mutable,
// but the reference to that FakeBuffer is immutable, i.e., the backing buffer
// is always the same, but the contents may change. Thus, while the accessor for
// the FakeBuffer is thread-safe, writes and reads to this buffer must be
// synchronized externally.
//
// Note: Currently the FakeImage only supports the NV12 image format.
