Bug 222556 Write a performance suite for DecoratingStyledCellLabelProvider
There is a suspicion that DecoratingStyledCellLabelProvider is much slower than DecoratingLabelProvider. We need a suite that tests scrolling a viewer with a DecoratingStyledCellLabelProvider both with and without colouring again one using a DecoratingLabelProvider.

/**
     * Returns the suite. This is required to use the JUnit Launcher.
     */
    public static Test suite() {
    	return new UIPerformanceTestSetup(new UIPerformanceTestSuite());
    }
    /**
     * Construct the test suite.
     */
    public UIPerformanceTestSuite() {
    	super();
        addTest(new ActivitiesPerformanceSuite());
        addTest(new PresentationPerformanceTestSuite());
        addTest(new WorkbenchPerformanceSuite());
        addTest(new ViewPerformanceSuite());
        addTest(new EditorPerformanceSuite());
        addTest(new TestSuite(CommandsPerformanceTest.class));
    }
