-/**
- * An implementation of SurfaceView that uses the dedicated surface for
- * displaying OpenGL rendering.
- * <p>
- * A GLSurfaceView provides the following features:
- * <p>
- * <ul>
- * <li>Manages a surface, which is a special piece of memory that can be
- * composited into the Android view system.
- * <li>Manages an EGL display, which enables OpenGL to render into a surface.
- * <li>Accepts a user-provided Renderer object that does the actual rendering.
- * <li>Renders on a dedicated thread to decouple rendering performance from the
- * UI thread.
- * <li>Supports both on-demand and continuous rendering.
- * <li>Optionally wraps, traces, and/or error-checks the renderer's OpenGL calls.
- * </ul>
- *
- * <div class="special reference">
- * <h3>Developer Guides</h3>
- * <p>For more information about how to use OpenGL, read the
- * <a href="{@docRoot}guide/topics/graphics/opengl.html">OpenGL</a> developer guide.</p>
- * </div>
- *
- * <h3>Using GLSurfaceView</h3>
- * <p>
- * Typically you use GLSurfaceView by subclassing it and overriding one or more of the
- * View system input event methods. If your application does not need to override event
- * methods then GLSurfaceView can be used as-is. For the most part
- * GLSurfaceView behavior is customized by calling "set" methods rather than by subclassing.
- * For example, unlike a regular View, drawing is delegated to a separate Renderer object which
- * is registered with the GLSurfaceView
- * using the {@link #setRenderer(Renderer)} call.
- * <p>
- * <h3>Initializing GLSurfaceView</h3>
- * All you have to do to initialize a GLSurfaceView is call {@link #setRenderer(Renderer)}.
- * However, if desired, you can modify the default behavior of GLSurfaceView by calling one or
- * more of these methods before calling setRenderer:
- * <ul>
- * <li>{@link #setDebugFlags(int)}
- * <li>{@link #setEGLConfigChooser(EGLConfigChooser)}
- * <li>{@link #setGLWrapper(GLWrapper)}
- * </ul>
- * <p>
- * <h4>Specifying the android.view.Surface</h4>
- * By default GLSurfaceView will create a PixelFormat.RGB_888 format surface. If a translucent
- * surface is required, call getHolder().setFormat(PixelFormat.TRANSLUCENT).
- * The exact format of a TRANSLUCENT surface is device dependent, but it will be
- * a 32-bit-per-pixel surface with 8 bits per component.
- * <p>
- * <h4>Choosing an EGL Configuration</h4>
- * A given Android device may support multiple EGLConfig rendering configurations.
- * The available configurations may differ in how many channels of data are present, as
- * well as how many bits are allocated to each channel. Therefore, the first thing
- * GLSurfaceView has to do when starting to render is choose what EGLConfig to use.
- * <p>
- * By default GLSurfaceView chooses a EGLConfig that has an RGB_888 pixel format,
- * with at least a 16-bit depth buffer and no stencil.
- * <p>
- * If you would prefer a different EGLConfig
- * you can override the default behavior by calling one of the
- * setEGLConfigChooser methods.
- * <p>
- * <h4>Debug Behavior</h4>
- * You can optionally modify the behavior of GLSurfaceView by calling
- * one or more of the debugging methods {@link #setDebugFlags(int)},
- * and {@link #setGLWrapper}. These methods may be called before and/or after setRenderer, but
- * typically they are called before setRenderer so that they take effect immediately.
- * <p>
- * <h4>Setting a Renderer</h4>
- * Finally, you must call {@link #setRenderer} to register a {@link Renderer}.
- * The renderer is
- * responsible for doing the actual OpenGL rendering.
- * <p>
- * <h3>Rendering Mode</h3>
- * Once the renderer is set, you can control whether the renderer draws
- * continuously or on-demand by calling
- * {@link #setRenderMode}. The default is continuous rendering.
- * <p>
- * <h3>Activity Life-cycle</h3>
- * A GLSurfaceView must be notified when to pause and resume rendering. GLSurfaceView clients
- * are required to call {@link #onPause()} when the activity stops and
- * {@link #onResume()} when the activity starts. These calls allow GLSurfaceView to
- * pause and resume the rendering thread, and also allow GLSurfaceView to release and recreate
- * the OpenGL display.
- * <p>
- * <h3>Handling events</h3>
- * <p>
- * To handle an event you will typically subclass GLSurfaceView and override the
- * appropriate method, just as you would with any other View. However, when handling
- * the event, you may need to communicate with the Renderer object
- * that's running in the rendering thread. You can do this using any
- * standard Java cross-thread communication mechanism. In addition,
- * one relatively easy way to communicate with your renderer is
- * to call
- * {@link #queueEvent(Runnable)}. For example:
- * <pre class="prettyprint">
- * class MyGLSurfaceView extends GLSurfaceView {
- *
- *     private MyRenderer mMyRenderer;
- *
- *     public void start() {
- *         mMyRenderer = ...;
- *         setRenderer(mMyRenderer);
- *     }
- *
- *     public boolean onKeyDown(int keyCode, KeyEvent event) {
- *         if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
- *             queueEvent(new Runnable() {
- *                 // This method will be called on the rendering
- *                 // thread:
- *                 public void run() {
- *                     mMyRenderer.handleDpadCenter();
- *                 }});
- *             return true;
- *         }
- *         return super.onKeyDown(keyCode, event);
- *     }
- * }
- * </pre>
