| /** |
| * <p>A display list records a series of graphics related operations and can replay |
| * them later. Display lists are usually built by recording operations on a |
| * {@link HardwareCanvas}. Replaying the operations from a display list avoids |
| * executing application code on every frame, and is thus much more efficient.</p> |
| * |
| * <p>Display lists are used internally for all views by default, and are not |
| * typically used directly. One reason to consider using a display is a custom |
| * {@link View} implementation that needs to issue a large number of drawing commands. |
| * When the view invalidates, all the drawing commands must be reissued, even if |
| * large portions of the drawing command stream stay the same frame to frame, which |
| * can become a performance bottleneck. To solve this issue, a custom View might split |
| * its content into several display lists. A display list is updated only when its |
| * content, and only its content, needs to be updated.</p> |
| * |
| * <p>A text editor might for instance store each paragraph into its own display list. |
| * Thus when the user inserts or removes characters, only the display list of the |
| * affected paragraph needs to be recorded again.</p> |
| * |
| * <h3>Hardware acceleration</h3> |
| * <p>Display lists can only be replayed using a {@link HardwareCanvas}. They are not |
| * supported in software. Always make sure that the {@link android.graphics.Canvas} |
| * you are using to render a display list is hardware accelerated using |
| * {@link android.graphics.Canvas#isHardwareAccelerated()}.</p> |
| * |
| * <h3>Creating a display list</h3> |
| * <pre class="prettyprint"> |
| * HardwareRenderer renderer = myView.getHardwareRenderer(); |
| * if (renderer != null) { |
| * DisplayList displayList = renderer.createDisplayList(); |
| * HardwareCanvas canvas = displayList.start(width, height); |
| * try { |
| * // Draw onto the canvas |
| * // For instance: canvas.drawBitmap(...); |
| * } finally { |
| * displayList.end(); |

| * HardwareCanvas hardwareCanvas = (HardwareCanvas) canvas; |
| * hardwareCanvas.drawDisplayList(mDisplayList); |
| * } |
| * } |
| * </pre> |
| * |
| * <h3>Releasing resources</h3> |
| * <p>This step is not mandatory but recommended if you want to release resources |
| * held by a display list as soon as possible.</p> |
| * <pre class="prettyprint"> |
| * // Mark this display list invalid, it cannot be used for drawing anymore, |
| * // and release resources held by this display list |
| * displayList.clear(); |
| * </pre> |
| * |
| * <h3>Properties</h3> |
| * <p>In addition, a display list offers several properties, such as |
| * {@link #setScaleX(float)} or {@link #setLeft(int)}, that can be used to affect all |
| * the drawing commands recorded within. For instance, these properties can be used |
| * to move around a large number of images without re-issuing all the individual |
| * <code>drawBitmap()</code> calls.</p> |
