+/**
+ * We use the BufferCache to reduce the overhead of exchanging GraphicBuffers with
+ * the server. If we were to simply parcel the GraphicBuffer we would pay two overheads
+ *     1. Cost of sending the FD
+ *     2. Cost of importing the GraphicBuffer with the mapper in the receiving process.
+ * To ease this cost we implement the following scheme of caching buffers to integers,
+ * or said-otherwise, naming them with integers. This is the scheme known as slots in
+ * the legacy BufferQueue system.
+ *     1. When sending Buffers to SurfaceFlinger we look up the Buffer in the cache.
+ *     2. If there is a cache-hit we remove the Buffer from the Transaction and instead
+ *        send the cached integer.
+ *     3. If there is a cache miss, we cache the new buffer and send the integer
+ *        along with the Buffer, SurfaceFlinger on it's side creates a new cache
+ *        entry, and we use the integer for further communication.
+ * A few details about lifetime:
+ *     1. The cache evicts by LRU. The server side cache is keyed by BufferCache::getToken
+ *        which is per process Unique. The server side cache is larger than the client side
+ *        cache so that the server will never evict entries before the client.
+ *     2. When the client evicts an entry it notifies the server via an uncacheBuffer
+ *        transaction.
+ *     3. The client only references the Buffers by ID, and uses buffer->addDeathCallback
+ *        to auto-evict destroyed buffers.
