Akihiko Odaki ccebb9ae35 ui/cocoa: Use NSTrackingInVisibleRect 
I observed [NSTrackingArea rect] becomes de-synchronized with the view
frame with some unknown condition, and fails to track mouse movement on
some area of the view. Specify NSTrackingInVisibleRect option to let
Cocoa automatically update NSTrackingArea, which also saves code for
synchronization.

Fixes: 91aa508d02 ("ui/cocoa: Let the platform toggle fullscreen")

* 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.
