annotate src/joystick/darwin/SDL_sysjoystick.c @ 3924:7156c3b5536b SDL-1.2

Mac OS X joystick support: don't ignore kHIDUsage_GD_MultiAxisController devices, since they are probably joysticks, or joystick-like things. See 3Dconnexion's SpaceNavigator for an example of such a device: http://www.3dconnexion.com/products/3a1d.php Thanks to Laurence Passmore for the fix.
