Display lists are usually built by recording operations on a 2452036b19a5f82bc4d75cfcbff99c65df8d25a99bRomain Guy * {@link HardwareCanvas}. Replaying the operations from a display list avoids 2552036b19a5f82bc4d75cfcbff99c65df8d25a99bRomain Guy * executing application code on every frame, and is thus much more efficient.</p> 26daf98e941e140e8739458126640183b9f296a2abChet Haase * 2752036b19a5f82bc4d75cfcbff99c65df8d25a99bRomain Guy * <p>Display lists are used internally for all views by default, and are not 2852036b19a5f82bc4d75cfcbff99c65df8d25a99bRomain Guy * typically used directly. One reason to consider using a display is a custom 2952036b19a5f82bc4d75cfcbff99c65df8d25a99bRomain Guy * {@link View} implementation that needs to issue a large number of drawing commands. 3052036b19a5f82bc4d75cfcbff99c65df8d25a99bRomain Guy * When the view invalidates, all the drawing commands must be reissued, even if 3152036b19a5f82bc4d75cfcbff99c65df8d25a99bRomain Guy * large portions of the drawing command stream stay the same frame to frame, which 3252036b19a5f82bc4d75cfcbff99c65df8d25a99bRomain Guy * can become a performance bottleneck. To solve this issue, a custom View might split 3352036b19a5f82bc4d75cfcbff99c65df8d25a99bRomain Guy * its content into several display lists.
