This is really, really silly. Why do we need to set these at runtime like this. When would this not be what we want. Seems like we should have the getters return this ...

? the first one is required because starboard is removed from the application layer. The second is rather bizarre, but NSPathUtilties depends on it. Sure, NSPathUtiltities can do this instead.

They are both silly. It doesn't make sense that the application compositor sets any sort of file system stuff. Starboard should know how to do this itself. That would be more proper encapsulation ...

@bbowman any re-write on this should be considered through #1904. what we have is not ideal.

Darn. If there was some way to get a HSTRING out of the layer above this one, we could pass it via the NSString HSTRING bridge. That'd save us a whole copy :)

@DHowett-MSFT yes, and in fact, we do get the value from a HSTRING. But this being a temp folder, it is going to be copied when added to any file path.
