/**
* 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.
*
* 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.
*
* 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.
*
* Hardware acceleration
* 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()}.
*
* Creating a display list
*
* 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();
* }
* }
*
*
* Rendering a display list on a View
*
* protected void onDraw(Canvas canvas) {
* if (canvas.isHardwareAccelerated()) {
* HardwareCanvas hardwareCanvas = (HardwareCanvas) canvas;
* hardwareCanvas.drawDisplayList(mDisplayList);
* }
* }
*
*
* Releasing resources
* This step is not mandatory but recommended if you want to release resources
* held by a display list as soon as possible.
*
* // Mark this display list invalid, it cannot be used for drawing anymore,
* // and release resources held by this display list
* displayList.clear();
*
*
* Properties
* 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
* drawBitmap() calls.
*
*
* private void createDisplayList() {
* mDisplayList = DisplayList.create("MyDisplayList");
* HardwareCanvas canvas = mDisplayList.start(width, height);
* try {
* for (Bitmap b : mBitmaps) {
* canvas.drawBitmap(b, 0.0f, 0.0f, null);
* canvas.translate(0.0f, b.getHeight());
* }
* } finally {
* displayList.end();
* }
* }
*
* protected void onDraw(Canvas canvas) {
* if (canvas.isHardwareAccelerated()) {
* HardwareCanvas hardwareCanvas = (HardwareCanvas) canvas;
* hardwareCanvas.drawDisplayList(mDisplayList);

* // by x pixels to the right and redraw this view. All the commands
* // recorded in createDisplayList() won't be re-issued, only onDraw()
* // will be invoked and will execute very quickly
* mDisplayList.offsetLeftAndRight(x);
* invalidate();
* }
*
