| 212 | * This class provides an implementation of BnSurface (the "native" or |

| 214 | * LayerCleaner to ensure that mFlinger->onLayerDestroyed() is called for |
| 215 | * this layer when the BSurface is destroyed. |
| 216 | * |
| 217 | * The idea is to provide a handle to the Layer through ISurface that |
| 218 | * is cleaned up automatically when the last reference to the ISurface |
| 219 | * goes away. (The references will be held on the "proxy" side, while |
| 220 | * the Layer exists on the "native" side.) |
| 221 | * |
| 222 | * The Layer has a reference to an instance of SurfaceFlinger's variant |
| 223 | * of GLConsumer, which holds a reference to the BufferQueue. The |
| 224 | * getSurfaceTexture() call returns a Binder interface reference for |
