Due to limitations and bugs in SpiderMonkey's GC, wrapper objects for cairo contexts and similar may not get cleaned up immediately after repainting, leading to leaking memory. Explicitly disposing of such objects after they're not needed can clean up large portions of memory for cairo surfaces. https://bugzilla.gnome.org/show_bug.cgi?id=685513
