SimplGy / 2xBackground
Created Aug 12, 2013
Creates 1x and 2x background images. The 200% means that the pixel offsets will work on both the small and large images. Make sure your sprites line up exactly, so that the 2x images are exactly twice as big, twice as low, and twice as left.
View 2xBackground
//Support 1 and 2x image sizes
@mixin 2xBackground($url)
background-image: url($url + ".png")
@media only screen and (-webkit-min-device-pixel-ratio: 1.3), only screen and (min-device-pixel-ratio: 1.3)
background-image: url($url + "@2x.png")
background-size: 200%

Angular decoration makes $rootScope an event bus that cleans up after itself automaticaly. From:
View angularEventBus.js
$provide.decorator('$rootScope', ['$delegate', function($rootScope) {
$rootScope.prototype.$onRootScope = function(eventName, callback) {
var unbind = $rootScope.$on(eventName, callback);
this.$on('$destroy', unbind);

A few short methods that are helpful in navigating around angular scopes and watchers. For debugging or learning/exploring.
# A few short methods that are helpful in navigating around angular scopes and watchers.

# Given a scope, count its direct children
# Use the to tell (in the case of fancy nested directives) if you're cleaning up what you think you're cleaning up
