Map panning costs less script per frame, which matters most in Firefox for Android. The point-of-interest glow draws from a cached sprite, so Firefox no longer blurs a canvas shadow on every frame, and the live map caches its terrain in an offscreen layer, so a pan copies pixels and draws only the strip that comes into view. In desktop Firefox a pan frame drops from about 4 ms of render script to about 2.3 ms. The cost of compositing the canvas on a phone is not measured.
