* Hats and sliders are completely untested; the app I'm writing this for mostly
* doesn't use them and I don't own any joysticks with them.
*
* We don't bother to use event notification here. It doesn't seem to work
* with polled devices, and it's fine to call IDirectInputDevice8_GetDeviceData and
* let it return 0 events. */
