- fix dartdocs for addPerformanceOverlay - make PerformanceOverlayLayer honour its x, y, and height. - fix the y axis of PerformanceOverlayLayer to only show 3x16ms, since if it's more than 16ms it really doesn't matter what it is. - make the label on the PerformanceOverlayLayer show the worst time on record not the instantaneous time. - pin the fps to a maximum of 60Hz
