While you can turn on repaint counts for debugging redraws on composited layers, the count is not incremented when there is a repaint but the debug option to display the count is turned off. In order to facilitate https://bugs.webkit.org/show_bug.cgi?id=105024, we should always increment the repaint counter, even when the option is off.
