doesn't compile on macOS Sierra (10.12)

[Dave MacFarlane]

When trying to compile on MacOS 10.12, it fails because the file "QuickTime/QuickTime.h" isn't available.

A little googling suggests that the QuickTime API is deprecated and has been removed from 10.12, so the header file is no longer available..

I've some progress with Cocoa port. Stay tuned.

Just commenting it out allows it to compile and run, although the default background for the screen isn't painted the very first time. When a window has been created and removed, the background correctly appears and everything seems fine after that.
