* Check -[NSEvent modifierFlags] here.
*
* There is a NSEventType for an event notifying the change of
* -[NSEvent modifierFlags], NSEventTypeFlagsChanged but these operations
* are performed for any events because a modifier state may change while
* the application is inactive (i.e. no events fire) and we don't want to
* wait for another modifier state change to detect such a change.
*
* NSEventModifierFlagCapsLock requires a special treatment. The other flags
* are handled in similar manners.
*
* NSEventModifierFlagCapsLock
* ---------------------------
*
* If CapsLock state is changed, "up" and "down" events will be fired in
* sequence, effectively updates CapsLock state on the guest.
*
* The other flags
* ---------------
*
* If a flag is not set, fire "up" events for all keys which correspond to
* the flag. Note that "down" events are not fired here because the flags
* checked here do not tell what exact keys are down.
*
* If one of the keys corresponding to a flag is down, we rely on
* -[NSEvent keyCode] of an event whose -[NSEvent type] is
* NSEventTypeFlagsChanged to know the exact key which is down, which has
* the following two downsides:
* - It does not work when the application is inactive as described above.
* - It malfactions *after* the modifier state is changed while the
* application is inactive. It is because -[NSEvent keyCode] does not tell
* if the key is up or down, and requires to infer the current state from
* the previous state. It is still possible to fix such a malfanction by
* completely leaving your hands from the keyboard, which hopefully makes
* this implementation usable enough.
