This should make the optimization landed earlier in this bug apply for some of the NotifyThemeChanged() calls in nsWindow.cpp which are causing all the extra invalidations. If we know that system colors/fonts didn't change, we can avoid doing a bunch of reflow work and the patch from earlier in the bug can avoid re-rasterizing images too.
