/* For proper OS X applications, the resources are contained inside the application bundle.
|
|
So the strategy is to first check the application bundle for the file, then fallback to the current working directory.
|
|
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.
