MFT r20903: 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.
