SwitchCoreKeyboard crash

[Jeremy Huddleston]

Yep... I think that was it... the translation for our NSTabletPoint  
events (pen motion, tilt change, etc) was not being translated  
correctly, and a garbage event type was being sent to GetPointerEvents  
(which was sometimes KeyPress)

We use GetPointerEvents, GetKeyboardEvents, and GetProximityEvents for  
keyboard/mouse/proximity events.

What is GetKeyboardValuatorEvents?  Are the valuators being sent the  
same as with pointer?  How does the keyboard send a cursor location,  
pressure, or tilt?
