Switch to using a C-style cast to convert from screen number to
CGDirectDisplayID. While I would prefer to use C++ casting, the alternative
in this case is to use a typedef. Since -getDisplayID: is an Objective-C
method, it might as well use Objective-C conventions and (probably more
importantly) follow the Apple documentation.
