+ Note: One additional corner-case is if the resource is in a framework's resource bundle instead of the app.
+ We might want to use bundle identifiers, e.g. org.libsdl.sdl to get the bundle for the framework,
+ but we would somehow need to know what the bundle identifiers we need to search are.
+ Also, note the bundle layouts are different for iPhone and Mac.
