Switch DropShadow for RectangularGlow on lockscreen to improve performance

Browse source 
DropShadow requires actually sampling and blurring the source element, while RectangularGlow just creates a generic rectangle without caring about the source element. This greatly improves the speed of everything on the lockscreen, especially notifications (they aren't a laggy mess when you have a ton of them now)
