/**
* <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 DisplayListCanvas}. 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 DisplayListCanvas}. 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();
* DisplayListCanvas canvas = displayList.start(width, height);
* try {
* // Draw onto the canvas
* // For instance: canvas.drawBitmap(...);
* } finally {
* displayList.end();
* }

* if (canvas.isHardwareAccelerated()) {
* DisplayListCanvas displayListCanvas = (DisplayListCanvas) canvas;
* displayListCanvas.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>

* canvas.translate(0.0f, b.getHeight());
* }
* } finally {
