let's leave this off for now - there should be a nice way to test for it without
requiring VoiceOver (also it needs different OWNERS :p)

Done.

 gfx::NativeCursor NativeViewHostMac::GetCursor(int x, int y) {
   // Intentionally not implemented: Not required on non-aura Mac because OSX
   // will query the native view for the cursor directly. For NativeViewHostMac
   // in practice, OSX will retrieve the cursor that was last set by
   // -[RenderWidgetHostViewCocoa updateCursor:] whenever the pointer is over the
   // hosted view. With some plumbing, NativeViewHostMac could return that same
   // cursor here, but it doesn't achieve anything. The implications of returning
   // null simply mean that the "fallback" cursor on the window itself will be
   // cleared (see -[NativeWidgetMacNSWindow cursorUpdate:]). However, while the
   // pointer is over a RenderWidgetHostViewCocoa, OSX won't ask for the fallback
   // cursor.
