Bug 1540984: Pre-load theme header image and share across all windows. r=aswan For large header images, built-in memory caching does not work correctly, and we wind up seeing a flicker any time a new window is opened or becomes active. This patch caches the header image in an Image element at startup, and uses that element as the backing for the header image in all browser windows.
