Cursor.SetCursor fails on Mac Standalone if the hotspot is outside the cursor bounds. This works on windows fine (and can be useful in odd cases), so if its possible to make this work on Mac that would be great, otherwise it would probably be good to at least unify the functionality.

Just run the test scene and click the left mouse button. This should cause the cursor to change, but it won't, and will instead give an error in the log about the hotspot being outside the cursor bounds.
