Merge "Introduce ForceGpuRenderingPreferenceController"

        // animator duration scale

        // simulate secondary displays

        // smallest width

        // force gpu rendering

        controllers.add(new ForceGpuRenderingPreferenceController(context));

        // show gpu view updates

        // show hardware layers updates

        // debug gpu overdraw
