Also a couple of icon-related fixes:
* Use the proper context, since we need theming (this also means it cannot be stored in IconLoader, which is a singleton, and must be supplied).
* Force apply the standard size and tint, since app-provided icons may be arbitrary.
* Fix the schedule-time icon (the viewport size was incorrect).
