1. Aqua Cocoa Tk (native default since OS X 10.6)
2. Aqua Carbon Tk (original native, 32-bit only, deprecated)
3. X11 (supported by some third-party distributors, deprecated)
There are various differences among the three that affect IDLE
behavior, primarily with menus, mouse key events, and accelerators.
Some one-time customizations are performed here.
Others are dynamically tested throughout idlelib by calls to the
